Check Digit Verification of cas no

The CAS Registry Mumber 83167-04-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,6 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83167-04:
(7*8)+(6*3)+(5*1)+(4*6)+(3*7)+(2*0)+(1*4)=128
128 % 10 = 8
So 83167-04-8 is a valid CAS Registry Number.

Potential radiosensitizing agents. 5. 2-Substituted benzimidazole derivatives

Gupta,Larroquette,Agrawal

, p. 1342 - 1346 (1982)

A series of 2-substituted benzimidazoles and their derivatives have been synthesized and tested for their ability to selectively sensitize hypoxic Chinese hamster cells (V-79) toward the lethal effect of ionizing radiation. These compounds were prepared by reacting the 2-substituted benzimidazoles with 1,2-epoxy-3-methoxypropane in the presence of potassium carbonate. Reaction of the 2-nitro and 2-methylsulfonyl analogue with the epoxide also yielded a cyclized material, which was confirmed to be a benzimidazo[2,1-b]oxazole. In an attempt to increase the electron affinity, 5- or 6-nitro-2-substituted-benzimidazoles were also synthesized and then reacted with the epoxide to yield the corresponding 1-substituted derivatives. The results of the biological tests for the radiosensitizing activity of these agents against Chinese hamster cells (V-79) in culture indicated the 2-nitro-substituted analogues were the most effective sensitizers in this series.
