138560-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138560-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,6 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138560-56:
(8*1)+(7*3)+(6*8)+(5*5)+(4*6)+(3*0)+(2*5)+(1*6)=142
142 % 10 = 2
So 138560-56-2 is a valid CAS Registry Number.

Utility of β-(4-chlorobenzoyl)acrylic acid in heterocyclic synthesis
Eissa
, p. 1205 - 1214 (2007/10/03)
β-(4-Chlorobenzoyl)acrylic acid (1) proved to be a convenient precursor for the synthesis of a variety of heterocyclic systems through the reaction with compounds containing active methylene groups under Michael reaction conditions. Also, the reactivity o
