333740-79-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 333740-79-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,7,4 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 333740-79:
(8*3)+(7*3)+(6*3)+(5*7)+(4*4)+(3*0)+(2*7)+(1*9)=137
137 % 10 = 7
So 333740-79-7 is a valid CAS Registry Number.

Synthesis and bioactivity of some new 1-tolyl-3-aryl-4-methylimidazole-2- thiones
Saeed, Aamer,Batool, Mahira
, p. 143 - 154 (2008/04/01)
Three series of new 1-(isomeric methyl)benzoyl-3-arylthioureas (1-3a-i) were prepared from 2-, 3-, and 4-methylbenzoyl chlorides via isothiocyanate formation followed by treatment with various substituted anilines. The base-catalyzed condensation of thiou
