Check Digit Verification of cas no
The CAS Registry Mumber 37901-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,9,0 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 37901-95:
(7*3)+(6*7)+(5*9)+(4*0)+(3*1)+(2*9)+(1*5)=134
134 % 10 = 4
So 37901-95-4 is a valid CAS Registry Number.

A method for synthesizing intermediate telmisartan
-
Paragraph 0015; 0032; 0034; 0035; 0036, (2018/01/11)
The invention provides a totally novel synthetic method for the telmisartan intermediate 7-methyl-2-propyl-(1H)-benzimidazole-5-carboxylic acid. The synthetic method provided by the invention overcomes the defects of a lot of reaction steps and low total yield of synthetic processes for 7-methyl-2-propyl-(1H)-benzimidazole-5-carboxylic acid reported in literature and prepares the intermediate from 2-methyl-4-aminobenzoic acid, i.e., a compound 10, through three actions. Reduction of steps in the synthetic method enables product quality and yield to be substantially improved, production cost to be reduced, technological operation to be simplified and adverse influence on the environment to be substantially reduced.
