Check Digit Verification of cas no

The CAS Registry Mumber 1332928-55-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,2,9,2 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1332928-55:
(9*1)+(8*3)+(7*3)+(6*2)+(5*9)+(4*2)+(3*8)+(2*5)+(1*5)=158
158 % 10 = 8
So 1332928-55-8 is a valid CAS Registry Number.

Highly regio- and diastereoselective halohydroxylation of olefins: A facile synthesis of vicinal halohydrins

Zhang, Jinglei,Wang, Jie,Qiu, Zhuibai,Wang, Yang

experimental part, p. 6859 - 6867 (2011/10/02)

An efficient method for the synthesis of vicinal chlorohydrin or bromohydrin derivatives has been developed on the basis of direct halohydroxylation of various olefins with electrondonating or withdrawing substituent. The reactions were carried out under mild conditions in the presence of N-tosyl-l-threonine (NTsLT) as an acidic additive using chloramine T trihydrate, 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) or N-bromoacetamide (AcNHBr) as the halogen source, respectively, affording the corresponding vicinal halohydrins in good to high yields with excellent regio- and stereoselectivities.
