Interesting collaboration with CAS and Wikipedia
From the press release:
Welcome to Common Chemistry^™ from Chemical Abstracts Service (CAS), a
web resource that contains CAS Registry Numbers for approximately 7,800
chemicals of widespread general public interest. Common Chemistry is
helpful to non-chemists who know either a name or CAS Registry Number^®
of a common chemical and want to pair both pieces of information. The
CAS Registry Number is the
universally recognized unique identifier of chemical substances and is
often found on packaging and on articles of commerce.
While not a comprehensive CAS Registry Number lookup service, Common
Chemistry does provide a way to quickly and easily find names or CAS
Registry Numbers for chemicals of general interest.
CAS has collaborated with Wikipedia in
developing this resource and encourages you to use the Wikipedia link
(when available) or other sources of general information on chemistry,
to learn more about these chemicals.

Had a reference question about what free science dictionaries are online, so thought I would put some of that information up here.
tcaep.co.uk is published by scenta, in association with The Institute
of Physics, as part of a comprehensive range of websites to support
physics and physicists and others studying or working in the wider
fields of science, engineering and technology.
There is a lot of good basic information in astronomy, math, and tables of equations & constants.
This site provides links to glossaries, dictionaries,
and databases from various scientific disciplines. From the American Association for the Advancement of Science (AAAS).
From the Information Please
Almanac folks.This resource for children has an easy interface, and includes an on-line dictionary, encyclopedia, and a great games & quizzes section.
