ChemSpider
ChemSpider can be used to search, aggregate, and data mine publicly available chemical information, including data from PubChem. It can be searched by exact structure, substructure, and similarily structure as well as by chemical names and molecular formula, and limited by properties. ChemSpider has been enhanced with calculated properties from ACD Labs. Currently, it searches over 10,000,000 compounds.
Comments
Just fyi the ChemSpider database has now been expanded to over 16.5 Million compounds and there have been numerous updates to the fiunctionality of the system.

ACD/ChemSketch, both commercial and freeware, has been integrated to ChemSpider to allow access to both structure and substructure searching as well as access to the property prediction services. ACD/ChemSketch freeware has been downloaded by over 750,000 users and now all have access to ChemSpider via ChemSketch. Details regarding integration are available in a ChemSpider Technical Note (http://www.chemspider.com/TechnicalNotes.aspx) and the websearch addon can be downloaded from ACD/Labs website
