Check Digit Verification of cas no

The CAS Registry Mumber 1235968-11-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,9,6 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1235968-11:
(9*1)+(8*2)+(7*3)+(6*5)+(5*9)+(4*6)+(3*8)+(2*1)+(1*1)=172
172 % 10 = 2
So 1235968-11-2 is a valid CAS Registry Number.

A new method for the stereoselective construction of angular methyl group of fuzed cyclic ethers

Kadota, Isao,Kishi, Takayuki,Fujisawa, Yuka,Yamagami, Yuji,Takamura, Hiroyoshi

, p. 3960 - 3961 (2010)

A convenient method for the stereoselective construction of angular methyl group of fuzed cyclic ethers is described. Reactions of mixed thioacetals with Me2Zn/Zn(OTf)2 afforded the corresponding methylated products in good yields. Various protective groups such as MOM ether, benzylidene acetal, TBS ether, and pivaloyl group were stable under the reaction conditions.
