Check Digit Verification of cas no

The CAS Registry Mumber 90991-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,9 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90991-71:
(7*9)+(6*0)+(5*9)+(4*9)+(3*1)+(2*7)+(1*1)=162
162 % 10 = 2
So 90991-71-2 is a valid CAS Registry Number.

Kinetics and mechanism of nucleophilic displacements with heterocycles as leaving groups. Part 23. Studies at the borderlines between reactions proceeding (i) via free carbocations, (ii) via rate-determining formation of ion-molecule pairs, and (iii) via rate-determining nucleophilic ...

Evidenece is presented to demonstrate that at the borderline between first order reaction via the formation of free carbocations, both mechanism proceed independently, without merging.Similarly at the borderline between first-order (rate determining formation) and second-order (rate-determining nucleophilic attack) rections of intimate ion-molecule pairs, both reactions again proceed independently.
