Check Digit Verification of cas no

The CAS Registry Mumber 637332-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,3,3 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 637332-40:
(8*6)+(7*3)+(6*7)+(5*3)+(4*3)+(3*2)+(2*4)+(1*0)=152
152 % 10 = 2
So 637332-40-2 is a valid CAS Registry Number.

The ruthenium catalyzed formation of chiral dihydropyrrolones from α,β-unsaturated imines: Extending the reaction to terminal alkenes and investigating the formation of pyrroles as side-products

D?nnecke, Daniel,Imhof, Wolfgang

, p. 8499 - 8507 (2003)

The reaction of α,β-unsaturated imines derived from cinnamaldehyde with CO and various alkenes produces chiral 1,3-dihydropyrrolone derivatives. As a byproduct the formation of 2,3-disubstituted pyrroles is observed in every reaction. If the imines are re
