The CAS Registry Mumber 129088-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,8 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129088-65:
(8*1)+(7*2)+(6*9)+(5*0)+(4*8)+(3*8)+(2*6)+(1*5)=149
149 % 10 = 9
So 129088-65-9 is a valid CAS Registry Number.

Novel Ring Transformations of 5-Cyanouracils into 2-Thiocytosines, 2,4-Diaminopyrimidines, and Pyrimidopyrimidines by the Reaction with Thioureas and Guanidines

Hirota, Kosaku,Sajiki, Hironao,Kitade, Yukio,Maki, Yoshifumi

, p. 123 - 128 (2007/10/02)

The reaction of 5-cyanouracils with thioureas and guanidines causes novel pyrimidine-to-pyrimidine ring transformations.Thus, 1,3-disubstituted 5-cyanouracils (1) react with thiourea and guanidines to give the corresponding 5-carbamoyl-2-thiocytosines (2)
