Check Digit Verification of cas no

The CAS Registry Mumber 50834-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,8,3 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50834-09:
(7*5)+(6*0)+(5*8)+(4*3)+(3*4)+(2*0)+(1*9)=108
108 % 10 = 8
So 50834-09-8 is a valid CAS Registry Number.

Synthesis of some novel 2,4-disubstituted thiazoles as possible antimicrobial agents

, p. 261 - 267 (2008/09/18)

A series of novel 4-aryl/chloroalkyl-2-(2,3,5-trichlorophenyl)-1,3-thiazoles (5a-g and 7a-e) were synthesized by condensing 2,3,5-trichlorobenzenecarbothioamide with phenacyl bromide/dichloroacetone. 2,3,5-Trichlorobenzaldehyde thiosemicarbazone on treatment with phenacyl bromide afforded 4-aryl-2-(2,3,5-trichlorophenylidenehydrazino)-1,3-thiazoles (10a-g) in good yield. The newly synthesized compounds are characterized by IR, 1H NMR and mass spectral studies. These compounds were also screened for their antibacterial and antifungal activities. Preliminary results reveal that some of the synthesized compounds are showing promising antimicrobial activity.
