The chemical "2H-Benzimidazol-2-one, 1,3-dihydro-1-(phenylmethyl)-, [1-[[1-(phenylmethyl)-1H-benzimidazol-2-yl]azo]ethylidene]hydrazone" is a complex organic compound with the molecular formula C21H18N4O. It is derived from the benzimidazole class of heterocyclic compounds, which are known for their diverse range of applications in pharmaceuticals, agrochemicals, and dyes. This specific compound features a benzimidazolone core, which is a benzimidazole ring fused with a lactone group, and is further modified with a phenylmethyl group and an azo linkage to an ethylidene hydrazone moiety. The compound's structure suggests potential applications in the development of new drugs or as a synthetic intermediate in organic chemistry. Its complex nature also makes it a subject of interest for researchers studying the properties and reactions of benzimidazole derivatives.
The CAS Registry Mumber 1182-75-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 2 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1182-75: (6*1)+(5*1)+(4*8)+(3*2)+(2*7)+(1*5)=68 68 % 10 = 8 So 1182-75-8 is a valid CAS Registry Number.
