1252886-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1252886-15-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,8,8 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1252886-15:
(9*1)+(8*2)+(7*5)+(6*2)+(5*8)+(4*8)+(3*6)+(2*1)+(1*5)=169
169 % 10 = 9
So 1252886-15-9 is a valid CAS Registry Number.

Zinc-catalyzed domino hydroamination-alkyne addition
Biyikal, Mustafa,Porta, Marta,Roesky, Peter W.,Blechert, Siegfried
experimental part, p. 1870 - 1875 (2010/11/04)
The first zinc-catalyzed one-step synthesis of quaternary propargylamines with four different substituents is described. The domino hydroamination- alkyne addition reaction gives access to functionalized propargylamines under mild conditions.
