Calculate Digit Verification of CAS Registry Number 1191128-25:
(9*1)+(8*1)+(7*9)+(6*1)+(5*1)+(4*2)+(3*8)+(2*2)+(1*5)=132
132 % 10 = 2

The use of copper flow reactor technology for the continuous synthesis of 1,4-Disubstituted 1,2,3-triazoles

Bogdan, Andrew R.,Sach, Neal W.

experimental part, p. 849 - 854 (2009/11/30)

A library of 1,4-disubstituted 1,2,3-tri-azoles was synthesized using a copper flow reactor. Organic azides, generated in situ from alkyl halides and sodium azide, were reacted with acetylenes using the copper-catalyzed Huisgen 1,3-dipolar cy-cloaddition.
