Check Digit Verification of cas no

The CAS Registry Mumber 681850-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,8,5 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 681850-44:
(8*6)+(7*8)+(6*1)+(5*8)+(4*5)+(3*0)+(2*4)+(1*4)=182
182 % 10 = 2
So 681850-44-2 is a valid CAS Registry Number.

sym-triazines. 8. Synthesis and some reactions of 4,6-disubstituted 2-(1H-pyrrolyl)-1,3,5-triazines

Chesnyuk,Mikhailichenko,Zaplishnyi,Konyushkin,Firgang

, p. 339 - 348 (2008)

We have studied the reaction of 2,5-dimethoxytetrahydrofuran with 4,6-disubstituted 2-amino-1,3,5-triazines with the aim of obtaining novel coupled polyheterocyclic systems with potential bioactivity. Reaction conditions were optimized. A series of novel 4,6-disubstituted 2-(1H-1-pyrrolyl)-sym- triazines was obtained. It was found that the product yields depended on the nature of the substituent in the 4 and 6 positions of the triazine ring and on the reaction conditions.
