Check Digit Verification of cas no

The CAS Registry Mumber 872410-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,4,1 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 872410-99:
(8*8)+(7*7)+(6*2)+(5*4)+(4*1)+(3*0)+(2*9)+(1*9)=176
176 % 10 = 6
So 872410-99-6 is a valid CAS Registry Number.

Synthesis of partially hydrogenated 1,2,4-triazoloquinazolines by condensation of 3,5-diamino-1,2,4-triazole with aromatic aldehydes and dimedone

Lipson,Desenko,Borodina,Shirobokova,Musatov

, p. 114 - 119 (2005)

Three-component condensation of 3,5-diamino-1,2,4-triazole with aromatic aldehydes and dimedone in dimethylformamide gives 2-amino-5-aryl-8,8-dimethyl-5, 6,7,8,9,10-hexahydro[1,2,4]triazolo[3,2-b]quinazolin-6-ones. The reaction of 3,5-diamino-1,2,4-triazole with dimedone in the absence of aldehyde involves dimethylformamide as one of the carbonyl components to afford 2-amino-8,8-dimethyl-6,7,8,9-tetrahydro[1,2,4]triazolo[2,3-a]quinazolin-6-one. 2005 Pleiades Publishing, Inc.
