Check Digit Verification of cas no

The CAS Registry Mumber 880497-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,4,9 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 880497-74:
(8*8)+(7*8)+(6*0)+(5*4)+(4*9)+(3*7)+(2*7)+(1*4)=215
215 % 10 = 5
So 880497-74-5 is a valid CAS Registry Number.

The synthesis of tetradentate salens derived from (3R,4R)-N-substituted-3, 4-diaminopyrrolidines and their application in the enantioselective trimethylsilylcyanation of aromatic aldehydes

Serra, M. Elisa Silva,Murtinho, Dina,Goth, Albertino

, p. 315 - 319 (2013/04/24)

The in situ formed Ti(IV) complexes of pyrrolidine-based chiral salen ligands derived from natural l-tartaric acid were evaluated as catalysts in the enantioselective trimethylsilylcyanation of aromatic aldehydes. The different activity and selectivity of the catalysts in the formation of the products were found to be dependent on the N-substituent of the pyrrolidine.
