219639-21-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 219639-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 219639-21:
(8*2)+(7*1)+(6*9)+(5*6)+(4*3)+(3*9)+(2*2)+(1*1)=151
151 % 10 = 1
So 219639-21-1 is a valid CAS Registry Number.

Concepts for ligand design in asymmetric catalysis: A study of chiral amino thiol ligands

Anderson, James C.,Cubbon, Rachel,Harding, Michael,James, Daniel S.

, p. 3461 - 3490 (2007/10/03)

A series of new chiral sulfur-nitrogen chelate ligands, derived from amino acids, has been synthesised rationally. Fruitless experiments into catalytic asymmetric conjugate additions and desymmetrisation of meso- epoxides led us to analyse our ligands in
