Check Digit Verification of cas no

The CAS Registry Mumber 1233379-28-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,3,7 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233379-28:
(9*1)+(8*2)+(7*3)+(6*3)+(5*3)+(4*7)+(3*9)+(2*2)+(1*8)=146
146 % 10 = 6
So 1233379-28-6 is a valid CAS Registry Number.

Convenient synthesis of 5-substituted 2-amino[1,2,4]triazolo[1,5- a ][1,3,5]triazin-7(6 H)-ones from N -triazolide imidates and 1,2,4-Triazole-3,5- diamine

Khankischpur, Mehdi,Hansen, Finn K.,Geffken, Detlef

experimental part, p. 1645 - 1648 (2010/06/19)

A convenient and efficient synthesis of previously unreported N-triazolide imidates and their reaction with 1,2,4-triazole-3,5-diamine to give regioselectively 5-substituted 2-amino[1,2,4]triazolo[1,5-a][1,3,5]triazin-7(6H) -ones is described. The structure of the reported bicyclic compounds has been unambiguously proven by X-ray crystallography. Georg Thieme Verlag Stuttgart.
