Largest Collection of Proton NMR Spectra Now Available in SciFinder(R)

December 29, 2008

COLUMBUS, Ohio, Dec. 29 /PRNewswire/ — CAS, a division of the American
Chemical Society, announced today that scientists worldwide can now access
more than 23.8 million predicted proton Nuclear Magnetic Resonance (NMR)
spectra in SciFinder. SciFinder is the leading research and discovery tool and
the authoritative source of information on more than 41 million chemical
substances. These proton NMR spectra augment the 1.9 billion predicted and
experimental properties and data tags already available in SciFinder.

NMR spectroscopy is a widely used technique in determining the structure
of organic compounds. Researchers use proton NMR (also called 1H-NMR) as an
important analytical tool in characterizing molecules across a variety of
chemical research fields. For example, the spectra, now in SciFinder, are
widely used by synthetic chemists to identify and validate synthetic targets.

CAS is making the proton NMR spectra available through an agreement with
ACD/Labs, a respected organization that has supplied other property
information to CAS.

CAS, a division of the American Chemical Society, provides the world’s
largest and most current collection of chemical and related scientific
information, including the most authoritative database of chemical substances,
the CAS REGISTRY(SM). CAS combines these databases with advanced search and
analysis technologies to deliver the most complete, cross-linked, and
effective digital information environment for scientific research and
discovery, including such products as SciFinder, STN(R), STN Express(R), and
STN(R) AnaVist(TM), among others. The CAS web site is www.cas.org.
