CHEMICAL ABSTRACTSChemical Abstracts is the premier abstracting service for the field of chemistry and related areas. This is a huge database with over 700,000 documents added each year. CA abstracts are summaries of scientific discoveries reported in the published literature. They are intended to help you decide whether the original document is of interest. If it is, you can use the bibliographic heading material as the route to retrieve the document.

Chemical Abstracts covers around 8,000 journals.

CAS CHEMISTS CREATE ABSTRACTS FROM:

* journal articles (74%)* chemical and chemical engineering

patents (16%)

* conference proceedings (5%)* technical reports * dissertations * books

EACH ABSTRACT CONTAINS:

• complete bibliographic references • patent references (details of what was

patented by whom and the country in which the patent was issued)

• commonly used chemical substance names or molecular formulas

• chemical structure images (when available)

Many researchers unfamiliar with the content of the CAS databases assume that CA is strictly

"chemistry," and are astonished by the diversity of its coverage.

SCIFINDER SCHOLAR

• SciFinder Scholar is a desktop research tool designed especially for use by students and faculty to easily access the information in the Chemical Abstracts databases.

• Search by author name, research topic, substance identifier, chemical structure, or chemical reaction. (Sub-Structure searching ability is not available at U.C.)

SCIFINDER SCHOLAR• You can search the entire CA file

electronically with SciFinder from 1907 to the present.

• There are 15 computers in the Chemistry/Biology Library with the SciFinder software loaded on it. It is available during normal Library hours.

• The system is very easy to use and requires no training.

LICENSE AGREEMENT• We currently have a “three seat” license.

That means only three people at UC can use the database at the same time. If all sessions are in use you will get the following message.

• “SciFinder Scholar is unable to establish a session because all concurrent sessions on your campus are in use. Please try again later.”

SciFinder: Research Topic

SciFinder: Research Topic By default, Explore by Research Topic

searches for terms in the title, abstract, and index fields in both MEDLINE and Chemical Abstracts.

SciFinder Scholar applies truncation automatically. SciFinder retrieved hits for ‘inhibitor’ as well as ‘inhibition’, ‘inhibiting’, ‘inhibit’, ‘inhibitors’, etc.

SciFinder: Research Topic

Scifinder Scholar also searches synonyms because within SciFinder there is a very extensive synonym dictionary.

In this example, SciFinder also searched ‘human immunodeficiency virus’ and ‘HIV.’

CAS Registry Number

Each CAS Registry Number (RN) is a unique numeric identifier that contain up to 9 digits, divided by hyphens into 3 parts. Each RN designates only one substance. It has no chemical significance and is a link to a wealth of information about a specific chemical substance. There are over 32,000,000 RNs. Searching by RN is very effective.

CAS Registry Number

CAS Registry Numbers are systematic terms for substances and overcome all sorts of problems associated with nomenclature (e.g. different names for the same substance; substances which have very complex names only etc.). They are extremely important search terms for substances!
