Check Digit Verification of cas no

The CAS Registry Mumber 1068439-11-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,8,4,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1068439-11:
(9*1)+(8*0)+(7*6)+(6*8)+(5*4)+(4*3)+(3*9)+(2*1)+(1*1)=161
161 % 10 = 1
So 1068439-11-1 is a valid CAS Registry Number.

A versatile and convenient preparation of unsymmetrical diaryl disulfides

Demkowicz, Sebastian,Rachon, Janusz,Witt, Dariusz

body text, p. 2033 - 2038 (2009/04/03)

We have developed a convenient method for the synthesis of unsymmetrical diaryl disulfides under mild conditions in excellent yields. The described method is based on the straightforward preparation of 5,5-dimethyl-2-thioxo-1,3, 2-dioxaphosphorinane-2-sulfenyl bromide from readily available 5,5-dimethyl-2-sulfanyl-2-thioxo-l,3,2-dioxaphosphorinane or bis(5,5-dimethyl-2-thioxo-l,3,2-dioxaphosphorinan-2-yl) disulfide. The unsymmetrical diaryl disulfides can be obtained from aromatic thiol derivatives bearing electron-withdrawing or electron-donating groups. Thieme Stuttgart.
