1357075-63-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1357075-63-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,0,7 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1357075-63:
(9*1)+(8*3)+(7*5)+(6*7)+(5*0)+(4*7)+(3*5)+(2*6)+(1*3)=168
168 % 10 = 8
So 1357075-63-8 is a valid CAS Registry Number.

Diastereoselective preparation of (R)- and (S)-2-methoxy-2-phenylpent-3- ynoic acids and their use as reliable chiral derivatizing agents

Perez-Estrada, Salvador,Joseph-Nathan, Pedro,Jimenez-Vazquez, Hugo A.,Medina-Lopez, Manuel E.,Ayala-Mata, Francisco,Zepeda, L. Gerardo

, p. 1640 - 1652 (2012/04/23)

Benzoyl-S,O-acetals 1a and 1b were used as chiral auxiliaries to achieve the diastereoselective preparation of both enantiomers of 2-methoxy-2- phenylpent-3-ynoic acids (MPPAs). The latter were condensed with several chiral secondary alcohols and some primary amines to evaluate their potential as chiral derivatizing agents (CDAs). The 1H NMR spectra of the corresponding esters and amides showed strong consistency with the absolute configuration of the carbinol and amine moieties, whose observed ΔδL1 and ΔδL2 values were in the ranges of 0.1-0.4 and 0.02-0.12 ppm, respectively.
