Check Digit Verification of cas no

The CAS Registry Mumber 1221640-33-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,6,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1221640-33:
(9*1)+(8*2)+(7*2)+(6*1)+(5*6)+(4*4)+(3*0)+(2*3)+(1*3)=100
100 % 10 = 0
So 1221640-33-0 is a valid CAS Registry Number.

Ruthenium-Catalyzed Carbonylative Coupling of Anilines with Organoboranes by the Cleavage of Neutral Aryl C-N Bond

Xu, Jian-Xing,Zhao, Fengqian,Yuan, Yang,Wu, Xiao-Feng

, p. 2756 - 2760 (2020)

Herein, we report the first ruthenium-catalyzed Suzuki-type carbonylative reaction of electronically neutral anilines via C(aryl)-N bond cleavage. Without any ligand and base, diaryl ketones can be obtained in moderate to high yields by using Ru3/su
