4387-77-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4387-77-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4387-77:
(6*4)+(5*3)+(4*8)+(3*7)+(2*7)+(1*7)=113
113 % 10 = 3
So 4387-77-3 is a valid CAS Registry Number.

Synthesis of Polyhalogenated Butyryl Chlorides, Precursors of Pyrethroid Haloketenes

Martin, Pierre,Steiner, Eginhard,Bellus, Daniel

, p. 1947 - 1957 (2007/10/02)

The copper(I)-catalyzed free radical addition of halomethanes to acrylates and the addition of halogenated acetic acid derivatives to fluoro- or chloro-substituted ethylenes affords polyhalogenated butyric acid derivatives.Chlorides of these acids serve as precursors for haloketenes used in efficient syntheses of pyrethroids.
