128425-46-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128425-46-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,2 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128425-46:
(8*1)+(7*2)+(6*8)+(5*4)+(4*2)+(3*5)+(2*4)+(1*6)=127
127 % 10 = 7
So 128425-46-7 is a valid CAS Registry Number.

A New Pathway to (4-Aryl-1,3-butadiynyl)amines
Loeffler, Achim,Himbert, Gerhard
, p. 125 - 126 (2007/10/02)
(4-Aryl-1,3-butadiynyl)amines 5 are prepared in a two-step synthesis: Palladium(II) catalyzed cross-coupling of arylacetylenes 1 and 2-bromo-1,1-dichloroethene (2) furnishes the 4-aryl-1,1-dichloro-1-buten-3-ynes 3, which are transformed into 5 by two equ
