The Chemical Abstracts Service (CAS) is an index of scientific literature in chemistry and related fields that abstracts over 10,000 publications. It was established in 1907 and is now a division of the American Chemical Society. CAS indexes literature to help scientists benefit from colleagues' work, covering chemistry, biology, physics, medicine and more. It provides searching and access to references, reactions and other resources through products like Scifinder, STN and various databases.

5. Chemical Abstracts Services?
(CAS)
 Its is an index of the scientific literature
in chemistry and related fields, abstract
for almost all the articles.
 Available in print , microform, and CD-
ROM
 For online access scifinder scholar and
other databases of CAS

6. History
 Associated with the American Chemical Society in
since 1907 in columbus USA.
 In 1980 CA became Chemical Abstracts Service
(CAS) and an operating division of the American
Chemical Society.
 1995 CAS introduced Scifinder for direct access.

7. Cont…
 In 2010 STN introduce for depth of chemical
reaction and largest collection information
introduced STN.

8. Purpose
 The purpose of CA is to help scientists benefit from
the published work of their colleagues around the
world by monitoring, abstracting and indexing the
world's chemistry-related literature.

9. Strength of CAS
Abstracts (CA) aims to world all chemistry to
index -relevant publications
summarize for the Chemical Abstracts are 10,000
magazines , books
50 languages dissertations, conference
proceedings, and patents from 27 national
organizations and Two international
organizations.
