1189116-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1189116-41-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,1 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1189116-41:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*1)+(3*6)+(2*4)+(1*1)=163
163 % 10 = 3
So 1189116-41-3 is a valid CAS Registry Number.

Phosphine-catalyzed reaction of cyanohydrins with activated alkynes
Siby, Acetou,Loreau, Olivier,Taran, Frederic
experimental part, p. 2365 - 2370 (2010/02/28)
A new method for preparing α-cyanoacrylates and α-cyanoenones is described. The procedure uses a phosphine-catalyzed α-C addition of cyanide ion, generated in situ from cyanohydrins, to activated alkynes. An unexpected tandem reaction producing benzyliden
