1444259-54-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1444259-54-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,4,2,5 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1444259-54:
(9*1)+(8*4)+(7*4)+(6*4)+(5*2)+(4*5)+(3*9)+(2*5)+(1*4)=164
164 % 10 = 4
So 1444259-54-4 is a valid CAS Registry Number.

, p. 432 - 436 (2013/01/16)
O-Alkylation of pyrocatechol with 4-chloromethyl-1,3-dioxolane has been investigated. The ether formation selectivity is largely determined by the structure of the reactants and the conditions of the process. The inhibiting effect of the synthesized ortho
