Check Digit Verification of cas no

The CAS Registry Mumber 188677-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,7 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 188677-69:
(8*1)+(7*8)+(6*8)+(5*6)+(4*7)+(3*7)+(2*6)+(1*9)=212
212 % 10 = 2
So 188677-69-2 is a valid CAS Registry Number.

, p. 39 - 42 (1997)

The pyridazino[3,4-b]quinoxaline 12 was synthesized by the cyclization of the α-arylhydrazonoacylhydrazide 11. The reaction of compound 12 with phosphoryl chloride gave pyridazino[3,4-b]quinoxaline 13, whose reactions with sodium azide or cyclic secondary
