Check Digit Verification of cas no

The CAS Registry Mumber 99529-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,2 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99529-23:
(7*9)+(6*9)+(5*5)+(4*2)+(3*9)+(2*2)+(1*3)=184
184 % 10 = 4
So 99529-23-4 is a valid CAS Registry Number.

A mild and selective method for the hydrolysis of esters with trimethyltin hydroxide

Nicolaou,Estrada, Anthony A.,Zak, Mark,Lee, Sang Hyup,Safina, Brian S.

, p. 1378 - 1382 (2005)

Mild, selective, and efficient: A new method that involves the use of trimethyltin hydroxide for the hydrolysis of specific ester groups allows chemists to steer clear of unwanted elimination reactions and epimerizations. For example, the conversion of ester 1 into carboxylic acid 2 takes place under mild conditions, with nearly complete retention of stereochemical integrity. 1,2-DCE = 1,2-dichloroethane.
