CHEMLINE
Chemical Dictionary Online


CHEMLINE Defined

CHEMLINE is an online, interactive chemical dictionary file built
and maintained by the National Library of Medicine. It contains
entries for over 1.1 million chemical substances which are identified
by CAS Registry Numbers in the NLM databases. The main purpose of
CHEMLINE is to assist the user in searching bibliographic and data
files of NLM for information about these chemical substances. For a
given substance, CHEMLINE provided Registry Numbers and chemical
names, both of which can be used as search terms to enhance
retrieval in the subsequent search of other NLM databases. CHEMLINE
also allows the retrieval of structurally related compounds. The
data elements include: Registry Numbers, molecular formulas,
Chemical Abstracts index names, synonyms, various name and
structural fragments, and locator designations which point to other
NLM databases or to TSCAINV containing information on that
particular chemical substance. CHEMLINE also contains ring data
including the number of rings, ring sizes, ring elemental
compositions, and component line formulas.

CHEMLINE Accessed

CHEMLINE can be accessed by a variety of terminals connected to the
central computer facility at NLM in Bethesda, Maryland. Connection
is established via direct telephone line or nationwide networks with
access nodes located in many major cities. CHEMLINE is available at
NLM 24 hours a day, seven days a week.

CHEMLINE Searched

The user can search CHEMLINE for synonyms and Registry Numbers
associated with a particular substance by entering a chemical name
or mloecular formula. If the exact name of a chemical substance is
unknown, a search may be conducted using name fragments, formula
fragments, and/or ring analysis terms. This feature allows the user
to locate generic classes of compounds by searching at a
substructure level. The CHEMLINE record for sulfaquinoxaline follows:

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
