Check Digit Verification of cas no

The CAS Registry Mumber 259675-58-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,6,7 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 259675-58:
(8*2)+(7*5)+(6*9)+(5*6)+(4*7)+(3*5)+(2*5)+(1*8)=196
196 % 10 = 6
So 259675-58-6 is a valid CAS Registry Number.

A mild method for ring-opening aminolysis of lactones

Liu, Wenming,Xu, David D.,Repi?, Oljan,Blacklock, Thomas J.

, p. 2439 - 2441 (2001)

A mild and general method for lactone aminolysis is reported. Sodium 2-ethylhexanoate (NaEH) is found to serve both as a base and a catalyst in aminolysis of a variety of lactones by benzylamine hydrochloride. The nearly neutral pH conditions make this method applicable to many acid/base sensitive substrates.
