What's New from Chemical Abstracts Service
Ten Millionth Substance Available in
the REGISTRY File!
This molecule, written o
about by two scholars CH3'
from Japan, was the H
registered in the CAS
Chemical Registry Me Me
System and made
available in the REGISTRY File on STN
The REGISTRY File is the world's
largest substance identification file. Use
the REGISTRY File on STN to identify
substances and CAS Registry Numbers.
Then transfer your answers to
other databases with CAS Registry
Numbers on STN, like BEILSTEIN
AND BIOSIS PREVIEWS/RN, and
retrieve references on the substances.
Alloy Composition Displayed in the
CAS REGISTRY File!
Search for information about alloy composition!
You can specify the components
with exact percentages, with ranges, or
simply in their order of prevalence in the
alloy. Your answers will display a clear,
easy-to-read table that concisely
describes alloy compositions, showing
the components, their weight percentages,
and their CAS Registry Numbers.
Then, you can transfer your answers to
the CA File to retrieve CA abstracts
relevant to alloys, including patent
Fine-tuned alloy composition searching-now
in the REGISTRY File, with
easy transfer to the CA File for relevant
Polymer Searchers: Get Only the
Information You Want!
For multi-component substances, users
asked to see only the polymer CAS
Registry Number and molecular formula,
and not the associated monomers. We
listened. .and now you have more control
over the data you see and use! Now component
CAS Registry Numbers and
molecular formulas are identified so that
you can exclude them from your answers
if you choose. You'll get only the information
We Constantly Strive to Listen and
... to what searchers tell us they'd like to
see in a premier online search system. The
following new features make it easier for
you to search on STN:
* You can search for CAS Registry
Numbers without appending a field
code in any STN file in which
Registry Numbers are search terms.
* With SELECT CHEM, an option we
introduced last Fall, you can extract
CAS Registry Numbers and substance
names from your REGISTRY
File answers and search them in any
* Now you can use a brand new option,
SELECT NAME, the same way.
SELECT NAME extracts the
substance names from your
REGISTRY File answers and, like
SELECT CHEM, lets you search
them in any STN file.
