78874-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78874-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,8,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78874-40:
(7*7)+(6*8)+(5*8)+(4*7)+(3*4)+(2*4)+(1*0)=185
185 % 10 = 5
So 78874-40-5 is a valid CAS Registry Number.

Some Reactions of β-Aroylacrylic Acid Epoxides
Elkasaby, M. A.,Noureldin, N. A.
, p. 366 - 368 (2007/10/02)
β-Aroylacrylic acids (I) on reaction with hydrogen peroxide give α,β-epoxy-β-aroylacrylic acids (II) which on treatment with sodium hydroxide afford a mixture of arylmethyl 1,2-diketone (III) and arylmethyl glycollic acid (IV).The mixture is separated bei
