Check Digit Verification of cas no

The CAS Registry Mumber 138865-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,6 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138865-53:
(8*1)+(7*3)+(6*8)+(5*8)+(4*6)+(3*5)+(2*5)+(1*3)=169
169 % 10 = 9
So 138865-53-9 is a valid CAS Registry Number.

Asymmetric synthesis X III: The stereocontrolled synthesis of (R)-α-amino acids via a double chiral induction

Yao Zhong,Guilan,Changyou,Huri,Lanjun,Aiqiao

, p. 1087 - 1090 (2007/10/02)

The stereocontrolled synthesis of (R)-α-amino acids via a double chiral induction in alkylation of the ketimine derived from (+)-camphor and (+)-methyl glycinate which is a chiral match pair has been studied. (R)-α-amino acids with high optical purity 80-90% are obtained after hydrolysis of the alkylated products. We find that the chiral match which is the synergistic effect in a double chiral induction is very important to obtain the higher diastereoselectivity for the stereocontrolled synthesis.
