Calculate Digit Verification of CAS Registry Number 97319-48:
(7*9)+(6*7)+(5*3)+(4*1)+(3*9)+(2*4)+(1*8)=167
167 % 10 = 7
So 97319-48-7 is a valid CAS Registry Number.

Convenient synthesis of benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles with 1 mol% CuCl2·2H2O as catalyst in water

Wen, Li-Rong,Li, Shou-Lei,Zhang, Jian,Li, Ming

, p. 1581 - 1588 (2015)

A convenient and efficient procedure for the synthesis of benzo[4,5]thiazolo [2,3-c][1,2,4]triazoles has been developed via a tandem intermolecular C-N bond and intramolecular C-S bond formation sequence from o-bromo-arylisothiocyanates and aroylhydrazides. A series of benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles were provided in excellent overall yields with 1 mol% CuCl2·2H2O/1 mol% 1,10-phenanthroline as the catalyst and water as the solvent.
