40878-08-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40878-08-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,7 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40878-08:
(7*4)+(6*0)+(5*8)+(4*7)+(3*8)+(2*0)+(1*8)=128
128 % 10 = 8
So 40878-08-8 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
