129242-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129242-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,4 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129242-81:
(8*1)+(7*2)+(6*9)+(5*2)+(4*4)+(3*2)+(2*8)+(1*1)=125
125 % 10 = 5
So 129242-81-5 is a valid CAS Registry Number.

El-Bahaie, Said,Assy, Mohamed G.,Kadry, Azza
, p. 1049 - 1054 (2007/10/02)
2-(2-Arylvinyl)-4-mercapto-5-acetylpyrimidines IIIa-IIId were synthesized by condensation of cinnamoyl isothiocyanates Ia-Id with 2-aminopent-2-ene-4-one II.The synthesis of 4-methylthio-, 4-β-cyano)εthylthio- and 4-oxopyrimidines is also described.Compo
