Calculate Digit Verification of CAS Registry Number 1209922-89:
(9*1)+(8*2)+(7*0)+(6*9)+(5*9)+(4*2)+(3*2)+(2*8)+(1*9)=163
163 % 10 = 3

, p. 2918 - 2927 (2014/03/21)

A novel, copper(I)-promoted azide-alkene aerobic oxidative cycloaddition protocol was devel-oped for the regioselective synthesis of 1,4-disubsti-tuted/ 1,4,5-trisubstituted 1,2,3-triazoles by using azides and electron-deficient olefins under an oxygen atmosphere.
