Check Digit Verification of cas no

The CAS Registry Mumber 90631-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90631-66:
(7*9)+(6*0)+(5*6)+(4*3)+(3*1)+(2*6)+(1*6)=126
126 % 10 = 6
So 90631-66-6 is a valid CAS Registry Number.

Free Radical Substitution. Part 37. The Effect of Solvent on the Atomic Chlorination of 1-Substituted Butanes and Related Compounds

Potter, Alan,Tedder, John M.

, p. 1689 - 1692 (2007/10/02)

Experimental results reported in this paper show that the relative selectivity of atomic chlorination of 1-substituted butanes and related compounds is greatly influenced by the phase and by solvents.Solvents can be divided into three classes: (a) inert, (b) solvents which decrease the selectivity, and (c) solvents which increase the selectivity.The second group solvate the transition state and the third group solvate the chlorine atoms.
