CAS SciFinder-n Database: Using CAS SciFinder-n: Help, Tutorials, and Guides

The online version of the Chemical Abstracts index.

Basic Research Pathways

In CAS SciFindern, you may search for:

  • Substances - in other words chemicals, by name, molecular formula, or even by chemical properties like melting points, spectra, etc., as well as by drawing the structure. (more Help on Substance Searcching)
  • Reactions - as published in organic or organometallic chemistry journals. (more Help on Reaction Searching)
  • References - in other words, published articles, patents, papers, etc. by any part of the reference or by keywords in the titles, abstracts, or Concepts (subject tags) for the item. (more Help on Reference Searching)
  • Suppliers - to find out who sells a certain chemical
  • ...or combine these using ALL.  In this way, you could search for a keyword AND a chemical structure to find all publications that have a particular compound along with a particular topic.

You may also perform searches on

  • Biosequences - proteins or nucleotide strings by uploading standard BLAST, CDR, or Motif sequence
  • Retrosynthesis analysis by entering your desired product and analyzing synthetic routes that could get you to that product.

Quick overviews of basic functionality including

Help and Training may be given in short videos, or in text explanations with illustrated screen shots, while some is presented as a previously recorded webinar.

Training Seminars

Chemical Abstracts Service trainers provide regular web-seminar training opportunities.  Upcoming seminars' dates and registration information are available (be sure it's CAS SciFindern and not another CAS product!).
