Check Digit Verification of cas no

The CAS Registry Mumber 3509-49-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,0 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3509-49:
(6*3)+(5*5)+(4*0)+(3*9)+(2*4)+(1*9)=87
87 % 10 = 7
So 3509-49-7 is a valid CAS Registry Number.

Ligand Exchange Chromatography of Amino Alcohols. Use of Schiff Bases in Enantiomer Resolution

Gelber, Loren R.,Karger, Barry L.,Neumeyer, John L.,Feibush, Binyamin

, p. 7729 - 7734 (2007/10/02)

A new method for enantiomeric resolution of primary amino alcohols by HPLC is described involving derivatization to the salicylaldehyde Schiff base followed by ligand exchange chromatography (LEC) with chiral L-proline-bonded stationary phases.All of the α-amino alcohols with a hydroxyl substituent on the asymmetric carbon examined were resolved, including catecholamines and other β-hydroxyphenethylamines.The copper(II) ion employed in LEC serves to stabilize the Schiff base, whereas the derivative permits complexation in a manner favorable for resolution and enhanced detection.A possible structure for the mixed complex responsible for separation is suggested.From this structure, a correlation between elution order and configuration is proposed.
