Check Digit Verification of cas no

The CAS Registry Mumber 42003-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,0 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42003-85:
(7*4)+(6*2)+(5*0)+(4*0)+(3*3)+(2*8)+(1*5)=70
70 % 10 = 0
So 42003-85-0 is a valid CAS Registry Number.

Palladium-catalyzed three-component reaction of N-tosyl hydrazones, isonitriles and amines leading to amidines

Dai, Qiang,Jiang, Yan,Yu, Jin-Tao,Cheng, Jiang

, p. 16645 - 16647 (2015)

A palladium-catalyzed three-component reaction between N-tosyl hydrazones, aryl isonitriles and amines was developed, leading to amidines in moderate to good yields. This procedure features the rapid construction of amidine frameworks with high diversity and complexity. Ketenimines serve as intermediates, which encounter nucleophilic attack by amines to produce amidines.
