(4-Methoxy-3-nitro-phenyl)-o-tolyl-methanone is a complex organic compound with the molecular formula C15H13NO4. It is characterized by a methanone (ketone) functional group, which is a carbonyl group (C=O) bonded to two carbon atoms. The compound features a 4-methoxy-3-nitro-phenyl group, which includes a methoxy (-OCH3) substituent at the 4-position and a nitro (-NO2) group at the 3-position of the phenyl ring. The second part of the molecule is an o-tolyl group, which is a methyl-substituted phenyl ring (C6H4-CH3), with the methyl group located at the ortho position (adjacent to the carbonyl group). (4-Methoxy-3-nitro-phenyl)-o-tolyl-methanone is likely to be used in the synthesis of various pharmaceuticals, dyes, or other organic compounds due to its unique structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 66938-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,3 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66938-42:
(7*6)+(6*6)+(5*9)+(4*3)+(3*8)+(2*4)+(1*2)=169
169 % 10 = 9
So 66938-42-9 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.
