Check Digit Verification of cas no

The CAS Registry Mumber 131213-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,1 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131213-55:
(8*1)+(7*3)+(6*1)+(5*2)+(4*1)+(3*3)+(2*5)+(1*5)=73
73 % 10 = 3
So 131213-55-3 is a valid CAS Registry Number.

Design, synthesis and molecular docking of pyrazolo [3,4d] thiazole hybrids as potential anti-HIV-1 NNRT inhibitors

Kasralikar,Jadhavar,Goswami,Kaminwar,Bhusare

, p. 437 - 444 (2019/02/17)

A series of pyrazolo[3.4,d]thiazole hybrids 6 were synthesized from 5-arylidene-2-imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones 5. The 5-arylidene-2-imino-3-(4-arylthiazol-2-yl)-thiazolidin-4-ones 5 were synthesized from 2-amino-4-arylthiazoles 1 and 2-chloro-acetamido-4-arylthiazoles 2 via the formation of 2-imino-3-(4-substituted-arylthiazol-2-yl)-thiazolidin-4-ones 3 using substituted aldehydes 4. The 5-acrylidene derivative 5 on cyclisation with phenyl hydrazine give the pyrazolo [3, 4, d] thiazole derivatives 6. The obtained pyrazolo [3.4, d]thiazole derivatives were studied as anti-HIV-1 NNRT inhibitors. It was found that these compounds might have potent RT inhibition activity.
