Check Digit Verification of cas no

The CAS Registry Mumber 120491-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,9 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120491-97:
(8*1)+(7*2)+(6*0)+(5*4)+(4*9)+(3*1)+(2*9)+(1*7)=106
106 % 10 = 6
So 120491-97-6 is a valid CAS Registry Number.

Palladium-catalyzed decarbonylative C–N coupling to convert arylcarbamoyl chlorides to urea derivatives

Fan, Aihong,Peng, Jinsong,Zhou, Dun,Li, Xiang,Chen, Chunxia

supporting information, p. 1 - 12 (2020/07/27)

This paper describes the development of a palladium-catalyzed decarbonylative C–N coupling reaction that transforms arylcarbamoyl chlorides into tetrasubstituted ureas under a nitrogen atmosphere. A broad range of functional groups are compatible with this reaction, and diverse urea derivatives can be obtained with good to high yields.
