6037-42-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6037-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,3 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6037-42:
(6*6)+(5*0)+(4*3)+(3*7)+(2*4)+(1*2)=79
79 % 10 = 9
So 6037-42-9 is a valid CAS Registry Number.

SUPRAMOLECULAR ASYMMETRIC INDUCTION : A NEW CONCEPT APPLIED TO THE SUPPORTED ENANTIOSELECTIVE SYNTHESIS OF α-AMINO ACIDS

Calmes, Monique,Daunis, Jacques,Ismaili, Habiba,Jacquier, Robert,Koudou, Jean,et al.

, p. 6021 - 6032 (1990)

A polyacrylic resin with pendant chirality has been used as a chiral auxiliary.The prochiral ester enolate, reversibly linked to the polymer chain via a Schiff base, is surrounded by chiral pendants, allowing supramolecular asymmetric induction to occur.Amino acids with enantiomeric excesses up to 88-89percent could be synthesized from supported glycine t-butyl ester enolate by reaction with alkyl halides.Enantioselective protonation depends on the initial configuration of the supported amino acid.Alanine was obtained in 90percent ee by repetitive asymmetric protonation.
