ChemSpider makes available a database of chemical structures and predicted properties as well as providing access to a series of property prediction algorithms. Its database currently has over ten million compounds, and was written by 'ChemZoo' which currently appears not to have a website. A significant amount of the data is gathered from PubChem.
