RTECS Database on STN Enhanced with Aquatic and In Vitro Exposure Toxicity Data

Aquatic and in vitro exposure toxicity data is now available in RTECS (Registry of Toxic Effects of Chemical Substances) database. The new toxicity data is searchable in the Basic Index. It is also possible to search more specifically by Effect (EFF), Route (RTE), Organism (ORGN) and Duration (DUR).

The new data displays in the Toxicity data table as part of the TOX and TOXFULL formats, as well as in the ALL and certain other predefined display formats.


RTECS is a factual database that contains toxicity data and references for commercially important substances, including drugs and agrochemicals. The substance information and toxicology results are collected by the National Institute for Occupational Safety and Health, an agency of the U.S. Department of Health and Human Services.

CAS is enhancing the MARPAT database with additional backfile coverage from 1987 beginning with English- and German-language patents in March. Markush content for Japanese- and additional German-language patents from 1987 will be added throughout 2012.

STN Adds Chinese Patent Full Text Database - CNFULL

STN now includes CNFULL, the full-text of Chinese patent applications and patent specifications from 1985 onwards.

The Chinese Intellectual Property Office of the People's Republic of China has been the top authority for the number of patent applications. In recent years, over 500,000 applications were filed annually.

CNFULL database records contain bibliographic data including patent applicant, inventor, patent number, application, priority and related (PCT) application data, IPC and EPC classification codes, abstract and the full text of descriptions and claims. Records are available about a week after publication with the complete content. Abstracts are initially machine translated and replaced three months later by human translated text; descriptions and claims are machine translated.

Each database record contains all documents published for one application, displayed in order of appearance. Legal status data and family display formats from the INPADOCDB database are available. Online thesauri for the International Patent Classification (/IPC) and European Patent Classification (/EPC) are searchable.

The database is updated weekly and comprises over 4.5 million records and more than 3.8 million images. About 10,000 documents enter the database each week.

Numeric values of over 30 physical and chemical properties (/PHP) in almost 400 unit variants are searchable in all full text fields.

For additional information about this new databases, refer to the STN Database Summary Sheet or STNGuide (=> S CNFULL/DBN).
