Check Digit Verification of cas no

The CAS Registry Mumber 223394-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,3,9 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 223394-25:
(8*2)+(7*2)+(6*3)+(5*3)+(4*9)+(3*4)+(2*2)+(1*5)=120
120 % 10 = 0
So 223394-25-0 is a valid CAS Registry Number.

Diastereoselective aldol condensation with 2-(β- ethoxycarbonyl)oxazolidine derived from norephedrine. A chiral masked synthon of ethyl formylacetate

Garcia-Valverde, Maria,Nieto, Javier,Pedrosa, Rafael,Vicente, Martina

, p. 2755 - 2762 (2007/10/03)

Deprotonation of chiral masked synthetic equivalents of ethyl glyoxalate, derived from norephedrine, with a novel base formed by addition of tert-BuLi to tert-butyl formate, and subsequent reaction with aromatic aldehydes yields β-hydroxy esters in good yield and moderate to excellent diastereomeric excesses. Reductive transformation of the condensation products, and elimination of the chiral appendage leads to enantiomerically pure 2-aminomethyl-1,3-propanediol derivatives.
