I. Introduction
General Philosophy
CAS is committed to the global advancement of science through the
dissemination of scientific information to promote research
performed by individuals and teams of scientists. Daily, hundreds of
CAS scientists read scientific journal and patent literature and
thoroughly analyze and index the information so that it can be
consistently and easily found in the CAS Databases, thereby enabling
scientific research.
CAS is aware of the changing needs of researchers who rely on
scientific information to perform their daily tasks. With the
advances in technology, the wealth of information available to
scientists, and the race to new scientific breakthroughs, scientists
must be able to find and use scientific information with more ease
and flexibility.
Relying on the CAS Information Use Policies, CAS provides this ease
and flexibility. Customers will find that CAS permits the building
of Project directories/files and the sharing of information among
team members for the life of the Project. CAS permits the sharing
(but not aggregating or searching) of information globally within an
organization even with those who are not team members. To support
data mining, CAS permits the extraction of Metadata for use within
CAS or STNŽ provided tools without first displaying the data. The
use of CAS data in third party data mining tools is permitted as
long as CAS records are downloaded via STN AnaVist. All of these new
"freedoms" are aimed at further enabling the dissemination of
scientific information and the advancement of scientific research.
CAS Information Use Policies are aimed at supporting scientific
research performed by individuals and teams of scientists, while
protecting the business structure CAS is built upon. These Policies
are not aimed at providing a mechanism to aggregate CAS information
and offer it globally within an organization for use by all. CAS
does not permit the building of Databases that have wide and general
availability and no longer fulfill the purpose of individual or team
research that CAS permits but instead serve as a substitute for the
use of CAS Databases.
CAS Information Use Policies
These Policies apply to all forms of CAS information unless the
licenses for CAS products provide otherwise. These Policies are
subject to change at the discretion of CAS.
CAS information is copyrighted by the American Chemical Society
(ACS). All rights reserved. CAS' mission is to be the world leader
in disseminating chemical and related scientific information. These
Policies define appropriate and inappropriate uses of information
and apply to all forms of distribution (printed, electronic, CD, and
other media). These Policies are meant to be read in their entirety,
not taken individually out of the context of the other points.
Search results delivered in computer-readable form remain the
property of CAS. Recipient shall obtain CAS' specific written
permission for any uses of computer-readable search results other
than those listed under Authorized Use of CAS Information.
These Policies apply to scientists, engineers, librarians,
information professionals, and others working in their organization
that either search and retrieve information or ultimately consume
the information. They do not apply to vendors of CAS licensed
databases, marketing agents, gateway service operators, web search
operators, publishers, software developers, or other commercial
redistributors of information, whose use of this information must be
covered by separate agreements.
ACS does not make any warranties, express or implied, regarding CAS
information. In the event errors should appear, please report such
to CAS Customer Service.
II. Definitions
For the purposes of these Policies, the following terms will be used
as defined below:
Backup: a duplicate of search results and/or other information which
may be retained for a limited time as protection against loss in
delivery, inadvertent deletion, etc.
CASRN or CAS Registry NumberŽ: a unique numerical identifier created
and assigned to a chemical substance by CAS.
Data Element: the basic unit of identifiable and definable
information in a Database Record, such as the publication year,
abstract, document type, controlled vocabulary indexing, or chemical
structure.
Data Mining: A process using an automated approach to explore and
bring to the surface complex relationships. Data mining tools employ
algorithms that can look at numerous multidimensional data
relationships concurrently and cluster, classify, or build new data
associations.
Database: a collection of Records structured for search and
retrieval with a computer system.
Downloading: the process of capturing information in computer-
readable form from CAS Databases (whether from Databases made
available by CAS directly or by a vendor under a CAS license) or
created in computer-readable form from a corresponding printed form
or microform by keying or other means.
Information Broker: an individual or business that provides
searching and/or other data related services for external customers.
Information Professional: an individual who searches databases or
performs other information operations (e.g., analyses) on behalf of
the actual User of the information. An Information Professional who
is a member of a research or other business team for a purpose other
than these may also be a User.
Metadata: the individual Data Elements which describe an access
point or component of a Database Record.
Organization: a company, corporation, firm, enterprise, individual
government agency or institution (e.g. college or university) which
has the right to enter into agreements for services. A corporate
organization includes all its sites worldwide and all subsidiaries,
joint ventures, divisions, and other units of which it owns greater
than 50%.
Post Processing: the management or arrangement of records through
one or more steps of collating, sorting, reorganizing, formatting,
reformatting and editing the data and/or combining it with other
elements of information to present different textual or statistical
views. Data mining operations are not components of Post Processing.
Project: A research endeavor of defined scope, staffing, and limited
duration.
Record: a CAS accession number with any or all of its associated CAS
data (e.g., a CA abstract number with any or all of its associated
CAS data in bibliographic Databases or a CASRN with any or all of
its associated CAS data in substance Databases).
User: the individual who is the actual consumer and licensee of the
CAS information. This does not include an Information Professional
who acts only as an intermediary in the process of retrieving and/or
analyzing information for the User.
III. Authorized Use of CAS Information
a. A User, Information Professional or Information Broker may Post-
process CAS information as long as usage is consistent with the
other conditions described in these Policies. Non-CAS or non-STN
software may be used for these procedures which may include non-CAS
information. Attribution to ACS must be included.
b. Metadata from CAS Records may be downloaded for a Data Mining
procedure in compliance with CAS or STN Product licenses. The data
may be used in CAS or STN Data Mining Tools. To use CAS Metadata in
third party Data Mining Tools, you must download CAS Records through
STN AnaVist by using a "Download feature", and agree to the terms
and conditions for the use of this information. Any other uses of
CAS data in data mining procedures are prohibited and require that
you contact CAS. Any Records retained from the task are subject to
the limits specified in these Policies. CAS Records retained as a
result of the Data Mining process must be consistent with these
Policies and display the STN AnaVist copyright.
c. The building of searchable Project directories or Databases for
use by individuals and Project teams is permitted. Each User is
permitted to download and retain a maximum of 5,000 Records at any
given time for personal use or to share within a Project team for
the life of the Project. These Records may be obtained from more
than one CAS product as long as the 5,000 limit/User is not
exceeded.
d. A User may make electronic or print copies of CAS Records and
distribute them to others within the Organization where the User is
employed as long as the use constitutes reasonable use. Reasonable
use does not include general posting of results and/or sharing
results for the purpose of doing research for others. Copies of CAS
Records must display the ACS copyright.
e. An Information Professional may retain copies of search results
delivered to Users as Backup for a period not to exceed 1 year or
the maximum period required by the organization's record retention
policies.
f. An Information Broker, with the exception of the use of
SciFinder, may make and provide a copy of CAS information to a
customer outside its Organization, for whom it has been engaged to
conduct specific searches, provided that the ACS copyright notice is
placed on the material. A copy for Backup purposes may be kept for a
period either not exceeding 1 year, or otherwise determined by the
Information Broker's obligations to the customer. The User may
subsequently use the information according to these Policies.
g. A User may distribute CAS information outside of the Organization
as follows:
- in a bibliography of references, provided that the bibliography
is supplemental to the main content of the User's own
copyrighted or uncopyrighted work.
- in scientific publications such as a critical review, poster,
presentation, research report, patent, or other communication.
This publication should indicate that CAS information is
reprinted by permission of the American Chemical Society.
- in reports to the government when the information and the
reports are required by law or administrative policy.
h. A User or Organization may include, without a license and without
paying a fee, up to 10,000 CAS Registry Numbers or CASRNs in a
catalog, website, or other product for which there is no charge. The
following attribution should be referenced or appear with the use of
each CASRN: CAS Registry NumberŽ is a Registered Trademark of the
American Chemical Society. CAS recommends the verification of the
CASRNs through CAS Client ServicesSM.
i. A User who makes a legal copy of CAS information must make a
reasonable effort to prevent the theft or inadvertent illicit
dissemination of CAS intellectual property by displaying the
following ACS Copyright Notice conspicuously at least once on each
packet of information distributed by the User: Copyright Year by the
American Chemical Society. All Rights Reserved. (Use the year of
publication in the case of printed and microform services; in the
case of information derived from an online service, use either the
year provided by the online service or the current year.) For usage
exceeding or outside these restrictions, please refer to section V.
Special Permission.
IV. Unauthorized Use of CAS Information
All of the following uses are prohibited without prior written
permission from CAS:
a. A User may not disseminate, distribute, copy, or store any
portion of the CA Lexicon, without the prior written consent of CAS.
The CA Lexicon is the copyrighted intellectual property of the
American Chemical Society and is provided to assist in searching
Databases on STN.
b. A User may not copy or otherwise record all or portions of a
printed issue or Database with the purpose of, or the effect of,
avoiding subscription fees or use charges for that publication or
Database, except as provided in these Policies. This includes the
creation of centralized or networked Databases or directories of CAS
information.
c. CAS Records or Metadata may not be used in Data Mining with non-
CAS or non-STN tools unless the User or Information Professional has
downloaded the records via STN AnaVist. For uses of CAS Information
outside of this procedure the User or Information Professional must
contact CAS.
d. A User may not use automated programs for systematic retrieval of
CAS content to create or compile, directly or indirectly a
collection, compilation, database or directory. An example of
automated retrieval is a script written to extract and download CAS
data in batches.
e. A User may not redistribute any part of CAS Records or any CAS
Data Elements outside the Organization via the Internet or other
means except as specified in these Policies.
f. A government agency which receives legally required CAS
information from a User may not share, exchange, or redistribute
this information to another Organization, including another
government agency.
V. Special Permission
A User may also contact CAS to discuss special permission. Typical
uses that may be permitted, upon agreement, are the following:
1. One-time or periodic publication of CAS information in bulletins,
bibliographies, and other documents, either for distribution outside
the User's Organization or within the Organization if the use
exceeds what is described in these Policies.
2. Licensing of more than 10,000 CASRNs or use of any CAS
information other than what is permitted in these Policies.
3. If current or planned use of CAS information goes beyond what is
described in Section III of these Policies, please refer to the
Dialog Electronic Redistribution & Archiving (ERA) program. For
example, an Information Professional may pay to store backup copies
for a longer period, or a User may pay for the right to retain more
