CAS (Chemical Abstracts Service) is a division of the American Chemical Society and contains databases of chemical information. CAS Registry Numbers (often referred to as CAS RNs or CAS Numbers) are universally used to provide a unique, unmistakable identifier for chemical substances. A CAS Registry Number itself has no inherent chemical significance but provides an unambiguous way to identify a chemical substance or molecular structure when there are many possible systematic, generic, proprietary or trivial names.

Signaling Pathways Project
The Signaling Pathways Project is an integrated 'omics knowledgebase based upon public, manually curated transcriptomic and cistromic (ChIP-Seq) datasets involving genetic and small molecule manipulations of cellular receptors, enzymes and transcription factors. Our goal is to create a resource where scientists can routinely generate research hypotheses or validate bench data relevant to cellular signaling pathways.
ChemTHEATRE is an online resource for browsing and analyzing curated and user-contributed data sets of environmental contaminants. ChemTHEATRE also stores metadata of the samples and of the experimental methods.
