7716-42-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7716-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,1 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7716-42:
(6*7)+(5*7)+(4*1)+(3*6)+(2*4)+(1*2)=109
109 % 10 = 9
So 7716-42-9 is a valid CAS Registry Number.

Synthesis of 1-aryl-1H-indazoles via a ligand-free copper-catalyzed intramolecular amination reaction

Gao, Mingshan,Liu, Xiujie,Wang, Xianyang,Cai, Qian,Ding, Ke

, p. 1199 - 1204 (2011)

A general synthesis of 1-aryl-1-H-indazoles from o-halogenated aryl aldehydes or ketones and aryl hydrazines was described. This protocol included an intermolecular condensation and a ligand-free copper-catalyzed intramolecular Ullmann-type coupling react
