144409-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144409-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,0 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144409-81:
(8*1)+(7*4)+(6*4)+(5*4)+(4*0)+(3*9)+(2*8)+(1*1)=124
124 % 10 = 4
So 144409-81-4 is a valid CAS Registry Number.

REACTION OF KETENEALKYLSILYLACETALS WITH ACRYLONITRILE AND 2-CHLOROACRYLONITRILE
Quendo, A.,Rousseau, G.
, p. 1551 - 1560 (2007/10/02)
The Lewis acid catalyzed reaction of ketenealkylsilylacetals with acrylonitrile and 2-chloroacrylonitrile can take place via two pathways: a cycloaddition in CCl4-ZnBr2 and a Michaoel-type addition in CH2Cl2-ZnI2.
