Check Digit Verification of cas no

The CAS Registry Mumber 191601-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,6,0 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 191601-42:
(8*1)+(7*9)+(6*1)+(5*6)+(4*0)+(3*1)+(2*4)+(1*2)=120
120 % 10 = 0
So 191601-42-0 is a valid CAS Registry Number.

Synthesis of bridging electron transfer donor ligands

Chodorowski-Kimmes, Sandrine,Meyer, Thomas J.

, p. 3659 - 3662 (1997)

The syntheses of three bridging electron transfer donor ligands are described based on coupling of the electron transfer donor, N,N'-dimethylbenzidine with two 2,2'-bipyridines. Two different coupling strategies are used : coupling between an acid and an amine with formation of an amide, and nucleophilic coupling between an amine and an electrophilic bipyridine.
