Check Digit Verification of cas no

The CAS Registry Mumber 1433204-70-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,2,0 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1433204-70:
(9*1)+(8*4)+(7*3)+(6*3)+(5*2)+(4*0)+(3*4)+(2*7)+(1*0)=116
116 % 10 = 6
So 1433204-70-6 is a valid CAS Registry Number.

Synthesis of 2-selenyl(sulfenyl)benzofurans via Cu-catalyzed tandem reactions of 2-(gem-dibromovinyl)phenols with diorganyl diselenides(disulfides)

Liu, Jie,Chen, Wei,Wang, Lei

, p. 4723 - 4730 (2013)

An efficient synthesis of 2-selenyl(sulfenyl)benzofurans has been accomplished through a copper(i)-catalyzed tandem reaction of 2-(gem-dibromovinyl)phenols with diorganyl diselenides and disulfides in the presence of CuI/Mg/t-BuOLi in DMSO. Using this protocol, a variety of 2-selenyl(sulfenyl)benzofuran derivatives were obtained in good yields.
