Check Digit Verification of cas no

The CAS Registry Mumber 243969-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,9,6 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 243969-23:
(8*2)+(7*4)+(6*3)+(5*9)+(4*6)+(3*9)+(2*2)+(1*3)=165
165 % 10 = 5
So 243969-23-5 is a valid CAS Registry Number.

How does organic structure determine organic reactivity? The effect of ortho-dimethyl groups on the nucleophilic substitution and alkene-forming elimination reactions of ring-substituted cumyl derivatives

Amyes, Tina L.,Mizerski, Tadeusz,Richard, John P.

, p. 922 - 933 (1999)

The addition of a pair of ortho-methyl groups to ring-substituted cumyl derivatives to give the corresponding 2,6-dimethylcumyl derivatives X-1-Y leads to modest (5-fold) changes in the observed rate constant for reaction in 50:50 (v:v) trifluoroethanol-
