ChemIDplus, Now Updated With More Information

Pointed out on ResourceShelf.
ChemIDplus is the National Library of Medicine's chemical dictionary. It covers 370,000 chemicals (# from help file, higher than # in press release). It allows property searching, substructure searching, CAS RN searching -- all paid for by US tax dollars, and free to the world. They've recently updated the search and added more chemical property fields.
