Check Digit Verification of cas no

The CAS Registry Mumber 109430-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,3 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 109430-87:
(8*1)+(7*0)+(6*9)+(5*4)+(4*3)+(3*0)+(2*8)+(1*7)=117
117 % 10 = 7
So 109430-87-7 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS VIII: ENANTIONSELECTIVE SYNTHESIS OF (R) OR (S)-α-SUBSTITUTED BENZYLAMINES VIA CHIRAL PINANONE KETIMINE TEMPLATE

Yuanwei, Chen,Aiqiao, Mi,Xun, Xiao,Yaozhong, Jiang

, p. 1423 - 1430 (2007/10/02)

An excellent asymmetric synthesis of both (R) and (S)-α-substituted benzylamines in optical purity 90.4 - 99.9percent has been achieved by alkylation of a chiral ketimine, prepared from pinanone and benzylamine.Diastereoselectivity in the alkylation is not dependent on the alkyl halides.
