Calculate Digit Verification of CAS Registry Number 66938-46:
(7*6)+(6*6)+(5*9)+(4*3)+(3*8)+(2*4)+(1*6)=173
173 % 10 = 3
So 66938-46-3 is a valid CAS Registry Number.

Synthesis and anthelminthic acitivity of alkyl-(5-acyl-1-benzimidazol-2-yl) carbamates

Raeymackers,Van Gelder,Roevens,Janssen

, p. 586 - 594 (2007/10/05)

A series of alkyl-(5-acyl-l-H-benzimidazol-2-yl)-carbamates were prepared and screened for anthelminthic activity. Some of them were found to be fully active at low, atoxic oral dose levels against gastro-intestinal nematodes. The activity against Syphacia muris and Strongyloides ratta is indicated. From these studies methyl (5-benzoyl-1-H-benzimidazol-2-yl) carbamate (mebendazole) and methyl [5-(4-fluorobenzoyl)-1-H-benzimidazol-2-yl]carbamate (flubendazole) were selected for detailed investigation.
