162496-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162496-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,4,9 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 162496-58:
(8*1)+(7*6)+(6*2)+(5*4)+(4*9)+(3*6)+(2*5)+(1*8)=154
154 % 10 = 4
So 162496-58-4 is a valid CAS Registry Number.

A convenient synthesis of 3-arylbutanolides and 3-arylbutenolides
Gu, Jian-Xin,Holland, Herbert L.
, p. 3305 - 3315 (2007/10/03)
A series of 3-aryl-substituted butenolides and butanolides has been prepared in a common short synthetic sequence from the corresponding aryl aldehydes. The 3-arylbutanolides are prepared by cyclisation of 3-aryl-3- cyano-1-propanols, obtained by selectiv
