ChemSpider is a database of chemicals. ChemSpider is owned by the Royal Society of Chemistry. The database contains information on more than 100 million molecules from over 270 data sources including: Each chemical is given a unique identifier, which forms part of a corresponding URL. For example, acetone is 175, and thus has the URL http://www.chemspider.com/Chemical-Structure.175.html The ChemSpider database can be updated with user contributions including chemical structure deposition, spectra deposition and user curation. This is a crowdsourcing approach to develop an online chemistry database. Crowdsourced based curation of the data has produced a dictionary of chemical names associated with chemical structures that has been used in text-mining applications of the biomedical and chemical literature.
