Check Digit Verification of cas no

The CAS Registry Mumber 1286763-67-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,6 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1286763-67:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*6)+(3*3)+(2*6)+(1*7)=204
204 % 10 = 4
So 1286763-67-4 is a valid CAS Registry Number.

An efficient copper-catalyzed cross-coupling reaction of thiols with aryl iodides

Kao, Hsin-Lun,Chen, Chin-Keng,Wang, Yu-Jen,Lee, Chin-Fa

experimental part, p. 1776 - 1781 (2011/05/03)

Commercially available Cu2O powder is a very reactive catalyst for the coupling of thiols to aryl iodides. A variety of functional groups including esters, unprotected amines, alcohols, and heterocycles tolerate the reaction conditions. Moreover, di-ortho-substituted aryl iodides with sterically demanding substrates were also coupled to give the desired aryl thioethers in good to excellent yields. Copyright
