Check Digit Verification of cas no

The CAS Registry Mumber 1303963-54-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,9,6 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1303963-54:
(9*1)+(8*3)+(7*0)+(6*3)+(5*9)+(4*6)+(3*3)+(2*5)+(1*4)=143
143 % 10 = 3
So 1303963-54-3 is a valid CAS Registry Number.

, p. 508 - 512 (2011/04/24)

Aldol reactions of racemic enolizable dioxolan-protected α-substituted-β-ketoaldehydes with representative achiral ketones catalyzed by proline or 5-(2-pyrrolidine-2-yl)-1H-tetrazole in wet DMSO proceed with dynamic kinetic resolution (or via DYKAT with an α-substituted- β-alkoxyaldehyde) to give adducts with high dr and ee.
