Check Digit Verification of cas no

The CAS Registry Mumber 331963-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,9,6 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 331963-96:
(8*3)+(7*3)+(6*1)+(5*9)+(4*6)+(3*3)+(2*9)+(1*6)=153
153 % 10 = 3
So 331963-96-3 is a valid CAS Registry Number.

Metal-free preparation of cycloalkyl aryl sulfides via di-tert-butyl peroxide-promoted oxidative C(sp3)-H bond thiolation of cycloalkanes

Zhao, Jincan,Fang, Hong,Han, Jianlin,Pan, Yi,Li, Guigen

, p. 2719 - 2724 (2014)

A concise thiolation of the C(sp3)-H bond of cycloalkanes with diaryl disulfides in the presence of the oxidant di-tert-butyl peroxide (DTBP) has been developed. This reaction, without using any metal catalyst, tolerates varieties of disulfides and cycloalkanes substrates, giving good to excellent chemical yields, and thus provides a useful approach to cycloalkyl aryl sulfides from unactivated cycloalkanes.
