Check Digit Verification of cas no

The CAS Registry Mumber 157126-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,2 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157126-75:
(8*1)+(7*5)+(6*7)+(5*1)+(4*2)+(3*6)+(2*7)+(1*5)=135
135 % 10 = 5
So 157126-75-5 is a valid CAS Registry Number.

-

Paragraph 0025-0026, (2017/12/27)

The invention discloses a synthetic method of a triazole compound N-((5-(4-iodophenyl)-2H-1,2,4-triazol-3-yl)methyl)-N-propylpropan-1-amine. The preparation method comprises the steps of carrying out reduction, acylation, imidization, ring closure, Boc removal and alkylation reaction on a starting raw material: 3-(4-iodophenyl)ethyl acrylate, so as to obtain a target product 7. The triazole compound is used as a template micromolecule for synthesizing various compound libraries.
