Check Digit Verification of cas no

The CAS Registry Mumber 1429391-71-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,9,3,9 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1429391-71:
(9*1)+(8*4)+(7*2)+(6*9)+(5*3)+(4*9)+(3*1)+(2*7)+(1*1)=178
178 % 10 = 8
So 1429391-71-8 is a valid CAS Registry Number.

CaF2 catalyzed SN2 type chlorodehydroxylation of chiral secondary alcohols with thionyl chloride: A practical and convenient approach for the preparation of optically active chloroalkanes

Zhang, Junjie,Wang, Huanxia,Ma, Yun,Wang, Youming,Zhou, Zhenghong,Tang, Chuchi

, p. 2261 - 2263 (2013/05/09)

A CaF2 catalyzed chlorodehydroxylation of chiral secondary alcohols with thionyl chloride has been developed. The chlorination reaction is effective for a wide range of alcohols, generating the corresponding chloroalkanes in good yield with high optical purity with inversion of the original configuration of the alcohol.
