Check Digit Verification of cas no

The CAS Registry Mumber 20138-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,3 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20138-73:
(7*2)+(6*0)+(5*1)+(4*3)+(3*8)+(2*7)+(1*3)=72
72 % 10 = 2
So 20138-73-2 is a valid CAS Registry Number.

Catalyst and additive-free regioselective oxidative C-H thio/selenocyanation of arenes and heteroarenes with elemental sulfur/selenium and TMSCN

Feng, Chengtao,Peng, Ya,Ding, Guangrong,Li, Xiangxiao,Cui, Chang,Yan, Yizhe

supporting information, p. 13367 - 13370 (2018/12/13)

A regioselective oxidative C-H thio/selenocyanation of arenes and heteroarenes with TMSCN and elemental sulfur/selenium was demonstrated under catalyst-free and additive-free conditions. Dimethyl sulfoxide (DMSO) was employed as the mild oxidant as well as the solvent. The reaction is operationally simple and scalable with a broad substrate scope.
