Check Digit Verification of cas no
The CAS Registry Mumber 2131-39-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2131-39:
(6*2)+(5*1)+(4*3)+(3*1)+(2*3)+(1*9)=47
47 % 10 = 7
So 2131-39-7 is a valid CAS Registry Number.

A computational analysis of the kinetic characteristics of the isomeric transformations of various peri-substituted polymethylnaphthalenes was undertaken on the basis of the determination of relative stability of isomeric methyl-substituted naphthalenonium ions and the effect of the charge factor.The role of steric factors in the investigated processes was assessed.The obtained calculated results agree with experimental data for various acid systems.
