Check Digit Verification of cas no

The CAS Registry Mumber 134890-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,9 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134890-49:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*0)+(2*4)+(1*9)=146
146 % 10 = 6
So 134890-49-6 is a valid CAS Registry Number.

Synthesis and study of antimicrobial activities of variously chlorosubstituted 3-phenyloctahydropyrimido-[3,4-a]-s-triazines

Menager,Loire,Lafont,Champeyrol,Delabos,Garnier,Combet Farnoux

, p. 79 - 84 (2007/10/02)

These compounds were synthesised, via a double Mannich reaction between 5,5-diethyl-4-iminobarbituric acid, formaldehyde and primary chlorophenylamines. The by-products of the reaction, 1,3,5,-triarylhexahydro-s-triazines and monoamino-methylpyrimidinediones, were identified and their formation discussed. It was shown that the extracyclic nitrogen atom underwent the first aminomethylation and that the substitution of the intracyclic nitrogen atom, inducing ring closure, took place in a second step. All the compounds exhibited antimicrobial activities against bacteria and/or fungi and the derivative presenting a chlorine atom in the 3-position on the nucleus was as active as miconazole nitrate agonist T rubrum and E floccosum.
