5451-78-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5451-78-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,5 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5451-78:
(6*5)+(5*4)+(4*5)+(3*1)+(2*7)+(1*8)=95
95 % 10 = 5
So 5451-78-5 is a valid CAS Registry Number.

A new synthetic method for haloalkyl carboxylic esters from the radical ring cleavage of cyclic acetals with haloform
Hai-Xia, Lin,Liang-Heng, Xu,Nai-Ju, Huang
, p. 303 - 306 (2007/10/03)
A one-pot reaction of cyclic acetals with haloform catalyzed by AIBN(2,2'-azobisisobutyronitrile) provides a novel convenient way to prepare directly haloalkyl carboxylic esters in good yields.
