Check Digit Verification of cas no

The CAS Registry Mumber 1059629-79-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,9,6,2 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1059629-79:
(9*1)+(8*0)+(7*5)+(6*9)+(5*6)+(4*2)+(3*9)+(2*7)+(1*9)=186
186 % 10 = 6
So 1059629-79-6 is a valid CAS Registry Number.

Synthesis of pyrazino[1,2-a]benzimidazol-1(2H)ones via a microwave assisted Buchwald-Hartwig type reaction

Alen, Jo,Robeyns, Koen,De Borggraeve, Wim M.,Van Meervelt, Luc,Compernolle, Frans

, p. 8128 - 8133 (2008)

A convenient synthesis of substituted pyrazino[1,2-a]benzimidazol-1(2H)ones starting from 3,5-dichloropyrazinones has been accomplished. Various 3-anilino-pyrazinones were easily converted to the desired tricyclic structures by applying a microwave assisted Buchwald-Hartwig type cyclization.
