Opis
(Description):
informacijski servis CAS (Chemical Abstracts Service), indeksira in dnevno ažurira
svetovno kemijsko literaturo in patente. Dostop do baz podatkov CAS prek
sistemov STN International(SM), SciFinder® in STN
Easy®, omogoča iskanje v bazah podatkov: Chemical Abstracts (CA), s približno
16 milijoni izvlečkov in CAOLD, z več kot 3 milijone izvlečkov (1907-1966). Baza
podatkov kemičnih substanc (CAS Registry) trenutno vsebuje več kot 24
milijonov zapisov substanc. Dnevno dodani zapisi v bazo podatkov “CAS Registry”: približno
2,500 dokumentnih zapisov in 11,000 registracij substanc. Septembra 2009 je CAS
registriral 50-milijonto substanco. Prek omrežja STN je
na voljo več kot 200 znanstveno-tehničnih baz podatkov. Znastveno-tehnična
informacijska servisa: FIZ
Karlsruhe, Nemčija in Japan

Description
(Opis): The information service CAS offers the CAS REGISTRYSM - the largest collection of substance information - as well as indexed references
from more than 10,000 major scientific journals and 59 patent authorities around the world. CAS databases are:
updated daily, built and quality controlled by CAS scientists, accessed via SciFinder and STN - award-winning search and analysis tools,
a single resource for both patents and journal articles. CAS registers 50 Millionth Substance:
On September 7, 2009 CAS Registry Number 1181081-51-5 was assigned to a novel arylmethylidene heterocycle. CAS REGISTRY, the most comprehensive and high-quality compendium of
publicly disclosed chemical information, now includes 50 million organic and inorganic substances. Read the recent
news release. CAS launches free Web-based resource "Common Chemistry" for General Public:
common chemistryTM is a resource providing information on approximately 7800 chemical substances of general and widespread interest. It is helpful to non-chemists
who know a chemical name or CAS Registry Number of a common everyday chemical and want to pair both pieces
of information. Read the news release. [Record: August 06, 2000][Updating:

Dr. Hornak is Professor of Chemistry and Imaging Science at the Rochester Institute of Technology where he teaches
courses in magnetic resonance imaging, nuclear magnetic resonance spectroscopy, and analytical chemistry. He is also
Director of the Magnetic Resonance Laboratory, a research and development laboratory on the RIT campus. His
research interests include multi-spectral tissue classification with magnetic resonance images, in vivo low frequency
electron spin resonance of free radicals, magnetic resonance hardware development, and magnetic resonance imaging
of materials. Dr. Hornak received his Ph.D. from the University of Notre Dame and has done postdoctoral work at Cornell
University. He is author of more than 160 published and conference papers on magnetic resonance related topics.[Record:
