Check Digit Verification of cas no

The CAS Registry Mumber 1357932-30-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,9,3 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1357932-30:
(9*1)+(8*3)+(7*5)+(6*7)+(5*9)+(4*3)+(3*2)+(2*3)+(1*0)=179
179 % 10 = 9
So 1357932-30-9 is a valid CAS Registry Number.

An efficient and practical synthesis of aryl and hetaryl α-keto esters

Raghunadh, Akula,Meruva, Suresh Babu,Kumar, Nuka Anil,Kumar, Gudla Santosh,Rao, L. Vaikunta,Syamkumar

supporting information; experimental part, p. 283 - 289 (2012/03/26)

A general and highly efficient method was developed for the synthesis of -keto esters by oxidative esterification of 2,2-dibromo-1-(het)arylethanones by sequential treatment with dimethyl sulfoxide and an alkanol. The versatility of the reaction was established by synthesizing a range of -keto esters by treatment of 2,2-dibromoethanones, derived from aryl or hetaryl ketones, with di-methyl sulfoxide and a cyclic or acyclic primary or secondary alcohol. The mechanism of the reaction was established by means of a detailed study. Georg Thieme Verlag Stuttgart · New York.
