Check Digit Verification of cas no

The CAS Registry Mumber 479623-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,9,6,2 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 479623-43:
(8*4)+(7*7)+(6*9)+(5*6)+(4*2)+(3*3)+(2*4)+(1*3)=193
193 % 10 = 3
So 479623-43-3 is a valid CAS Registry Number.

(S)-leucine and [(S)-1-(1-naphthyl)ethyl]amine as chiral building blocks for a bifunctional system - Synthesis of a new chiral stationary phase and evaluation of its biselector properties in the HPLC resolution of racemic compounds

Iuliano, Anna,Attolino, Emanuele,Salvadori, Piero

, p. 3523 - 3529 (2007/10/03)

Two selectors derived from [(S)-1-(1-naphthyl)ethyl]amine and (S)-leucine have been chemically bonded to one another and the resulting chiral auxiliary linked covalently to silica gel, to produce a new chiral stationary phase (CSP) for the HPLC resolution of enantiomers. The CSP is able to separate the enantiomers of some selected racemic compounds: both those resolved by Oi's CSP {derived from [1-(1-naphthyl)ethyl]amine} and those enantiodiscriminated by Pirkle's CSP [derived from N-(3,5-dinitrobenzoyl)leucine]. The results obtained demonstrate that the CSP possesses the properties of an efficient biselector system.
