Check Digit Verification of cas no

The CAS Registry Mumber 143121-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,2 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143121-72:
(8*1)+(7*4)+(6*3)+(5*1)+(4*2)+(3*1)+(2*7)+(1*2)=86
86 % 10 = 6
So 143121-72-6 is a valid CAS Registry Number.

Asymmetric Strecker reaction of ketoimines catalyzed by a novel chiral bifunctional N,N′-dioxide

Huang, Xiao,Huang, Jinglun,Wen, Yuehong,Feng, Xiaoming

, p. 2579 - 2584 (2007/10/03)

A novel bifunctional N,N′-dioxide derived from L-prolinamide was employed to catalyze the enantioselective Strecker reaction of a range of N-tosyl ketoimines, and an effective additive was used to improve the reactivity (up to 99% yield) as well as the en
