Check Digit Verification of cas no
The CAS Registry Mumber 142653-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142653-22:
(8*1)+(7*4)+(6*2)+(5*6)+(4*5)+(3*3)+(2*2)+(1*2)=113
113 % 10 = 3
So 142653-22-3 is a valid CAS Registry Number.

Synthetic applications of the [2+2] cycloaddition products of ketene alkylsilylacetals with acrylonitrile
Rousseau,Quendo
, p. 6361 - 6370 (2007/10/02)
2-Cyanocyclobutane alkylsilylacetals, obtained by a [2+2] cycloaddition reaction of ketene alkylsilylacetals and acrylonitrile, have allowed the synthesis of 2-cyanoclobutanones, 4-chloro-4-cyanobutanoates and 4-cyanobutanoates by respectively acidic cata
