4. SciFinder ® : Part of the process™ 2006 Edition Several new structure search capabilities are available Similarity Searching Powerful new query tools New and improved structure search options

5. SciFinder ® : Part of the process™ 2006 Edition Similarity search ranks all compounds in the CAS Registry SM database via the Tanimoto algorithm Compounds with highest scores included in results Similarity search is complementary to substructure search Similarity searching allows scientists to find new types of answers to their structure questions

6. SciFinder ® : Part of the process™ 2006 Edition The Tanimoto algorithm utilizes various chemical descriptors Atoms and their direct attachments Atom sequences Bond sequences Degree of connectivity Type of ring fusion Element counts Atom counts Ring counts

7. SciFinder ® : Part of the process™ 2006 Edition An example of a Tanimoto score calculation QS = Number of query descriptors = 143 FS = Number of file substance descriptors = 169 C = Number of descriptors common to both = 139 Score = 100 * C = 100 * 139 = 80 (QS + FS – C) (143 + 169 – 139)

8. SciFinder ® : Part of the process™ 2006 Edition The fewer the differences between query and answer, the higher the score Query

9. SciFinder ® : Part of the process™ 2006 Edition Similarity searching is accessed via Get Substances

10. SciFinder ® : Part of the process™ 2006 Edition An analysis is performed based on similarity scores

11. SciFinder ® : Part of the process™ 2006 Edition Selected answers are presented in similarity score order

12. SciFinder ® : Part of the process™ 2006 Edition Substances with lower scores show increasing variance with the query

13. SciFinder ® : Part of the process™ 2006 Edition Substances with lower scores show increasing variance with the query

14. SciFinder ® : Part of the process™ 2006 Edition New structure query tools are available in SciFinder 2006 Draw a variable attachment point Draw a repeating group

15. SciFinder ® : Part of the process™ 2006 Edition These new tools are available in the structure editor tool palette New Variable Attachment Position tool New Repeating group tool

16. SciFinder ® : Part of the process™ 2006 Edition New search options allow scientists to control the relevancy of their answer set Eliminate substances with no literature references Describe literature roles of resulting substances Only retrieve commercially available substances Control the type of substance retrieved by its chemical classification
