Check Digit Verification of cas no

The CAS Registry Mumber 1243541-74-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,5,4 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1243541-74:
(9*1)+(8*2)+(7*4)+(6*3)+(5*5)+(4*4)+(3*1)+(2*7)+(1*4)=133
133 % 10 = 3
So 1243541-74-3 is a valid CAS Registry Number.

Synthesis of some fused heterocycles based on thieno[2,3-B]pyridine and their antimicrobial activity

El-Essawy,Hawatta,Abdel-Megied,El-Sherbeny

, p. 325 - 333 (2010)

The reaction of 3-amino-4,6-dimethylthieno[2,3-b]pyridine-2-carbonitrile with ethylenediamine in the presence of a catalytic amount of carbon disulfide afforded 2-(4,5-dihydro-1H-imidazol-2-yl)-4,6-dimethylthieno-[2,3-b]pyridine-3- amine while its reaction with triethyl orthoformate followed by the reaction with hydrazine hydrate gave 4-imino-7,9-dimethylpyrido[3',2':4,5]thieno[3,2-d] pyrimidine-3(4H)-amine. These two derivatives underwent cyclocondensation reactions with commercially available reactants to afford new heterocycles containing the thieno[2,3-b]pyridine moiety. Some of the synthesized derivatives were tested for antimicrobial and antifungal activity. 2010 Springer Science+Business Media, Inc.
