Check Digit Verification of cas no
The CAS Registry Mumber 144426-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,2 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144426-57:
(8*1)+(7*4)+(6*4)+(5*4)+(4*2)+(3*6)+(2*5)+(1*7)=123
123 % 10 = 3
So 144426-57-3 is a valid CAS Registry Number.

, p. 4923 - 4926 (1992)
Starting from 4-chloropyridine and 2,6-dialkylphenoxides, 4-(3,5-dialkyl-4-hydroxyphenyl)pyridines are obtained via an electrochemical induced S(RN)1 reaction using 2,4'-bipyridine as a mediator (alkyl = pentyl, isopropyl, methyl). Quaternization of 4-(3,
