Check Digit Verification of cas no

The CAS Registry Mumber 252010-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,0,1 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 252010-73:
(8*2)+(7*5)+(6*2)+(5*0)+(4*1)+(3*0)+(2*7)+(1*3)=84
84 % 10 = 4
So 252010-73-4 is a valid CAS Registry Number.

A diamine-exchange reaction of dihydropyrazines

Yamaguchi, Tadatoshi,Ito, Shigeru,Iwase, Yukiko,Watanabe, Kenji,Harano, Kazunobu

, p. 1677 - 1680 (2007/10/03)

Dihydropyrazines reacted with 1,2-diamines to form tetraazadecalins as intermediates, and then the reaction proceeded forward to dissociate into alternate dihydropyrazine and diamine, or backward to dissociate into the starting materials in certain equilibrium. The product distribution is controlled by diamine-exchange equilibrium reaction. The various equilibrium reactions were analyzed by NMR spectroscopy.
