Check Digit Verification of cas no

The CAS Registry Mumber 87647-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,4 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87647-49:
(7*8)+(6*7)+(5*6)+(4*4)+(3*7)+(2*4)+(1*9)=182
182 % 10 = 2
So 87647-49-2 is a valid CAS Registry Number.

Synthesis of some new substituted thiosemicarbazides as potential antiviral agents

Singh,Bahadur

, p. 817 - 821 (2007/10/02)

Substituted thiosemicarbazides, synthesized by the condensation of substituted 5-chloro-diphenylamine-2-carboxylic acid hydrazides with appropriate arylisothiocyanates, have been tested for their antiviral activity against the plant virus, sunnhemp rosette virus, in vitro as well as in vivo and against the animal virus, ranikhet disease virus, in a stationary culture of chorioallantoic membranes of chick embryo. The majority of these compounds showed significant antiviral activity against both viruses. The structure-activity relationships have further been studied and are discussed.
