Check Digit Verification of cas no

The CAS Registry Mumber 170642-23-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,6,4 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 170642-23:
(8*1)+(7*7)+(6*0)+(5*6)+(4*4)+(3*2)+(2*2)+(1*3)=116
116 % 10 = 6
So 170642-23-6 is a valid CAS Registry Number.

Antimalarial activity of a new family of analogues of manzamine A

Winkler, Jeffrey D.,Londregan, Allyn T.,Hamann, Mark T.

, p. 2591 - 2594 (2007/10/03)

Manzamine A represents an important lead structure for the development of novel antimalarial chemotherapies. The synthesis and biological evaluation of a group of simplified analogues of manzamine A, which were designed to examine the roles of the A and D

The imine (+)-pseudoephedrine glycinamide: A useful reagent for the asymmetric synthesis of (R)-α-amino acids

Guillena, Gabriela,Najera, Carmen

, p. 181 - 183 (2007/10/03)

The new imine derived from Myers (+)-pseudoephedrine glycinamide can be diastereoselectively alkylated with alkyl halides at room temperature using NaOEt or LiO-tert-Bu as bases under phase transfer conditions. Hydrolysis to the corresponding alkylated products was easily achieved under mild conditions to afford (R)-α-amino acids.

A practical method for the synthesis of D- or L-α-amino acids by the alkylation of (+)- or (-)-pseudoephedrine glycinamide

Myers, Andrew G.,Gleason, James L.,Yoon, Taeyoung
