Check Digit Verification of cas no
The CAS Registry Mumber 145689-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 145689-41:
(8*1)+(7*4)+(6*5)+(5*6)+(4*8)+(3*9)+(2*4)+(1*1)=164
164 % 10 = 4
So 145689-41-4 is a valid CAS Registry Number.

Synthesis of dihalophenylacetic acids using aromatic nucleophilic substitution strategy
Kowalczyk, Bruce A.
, p. 1411 - 1414 (2007/10/03)
A simple synthetic strategy to dihalophenylacetic acids and specifically 3,5-difluorophenylacetic acid an important pharmaceutical intermediate was developed. The aromatic nucleophilic substitution of dihalofluorobenzenes using the anion of ethyl cyanoacetate yielded ethyl dihalophenylcyanoacetates. The basic decarboxylation of the ethyl dihalophenylcyanoacetates produced targeted dihalophenylacetic acids.
