Title: CHEMICAL ABSTRACTS


1
CHEMICAL ABSTRACTS
  • Chemical 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.

2
  • CAS CHEMISTS CREATE ABSTRACTS FROM
  • journal articles (74)
  • chemical and chemical engineering



    patents (16)
  • conference proceedings (5)
  • technical reports
  • dissertations
  • books

3
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)

16
FORMAT AND COVERAGE
  • Print Chemical Abstracts
  • 1907- to date
  • Electronic SciFinder Scholar
  • 1907- to date

17
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.)

18
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.

19
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
  • 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.

39
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.
53
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!

Structure Searching
We have the ability to do structure searching
but not sub-structure searching. Can search by
ACTUAL or EXACT structure only.
