Check Digit Verification of cas no

The CAS Registry Mumber 144285-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,8 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144285-04:
(8*1)+(7*4)+(6*4)+(5*2)+(4*8)+(3*5)+(2*0)+(1*4)=121
121 % 10 = 1
So 144285-04-1 is a valid CAS Registry Number.

COPPER(II) IN ORGANIC SYNTHESIS. X. THE IMPORTANCE OF STERIC HINDRANCE IN THE DESIGN OF CHIRAL TRIDENTATE LIGAND COPPER(II) CATALYSTS FOR ENANTIOSELECTIVE MICHAEL REACTIONS

Desimoni, Giovanni,Faita, Giuseppe,Mellerio, Giorgio,Righetti, Pier Paolo,Zanelli, Claudio

, p. 269 - 273 (2007/10/02)

Several copper(II) complexes with tridentate chiral ligands derived from 2-substituted 2-aminoethanols have been tested as catalysts for enantioselective Michael reactions.The degree of enantioselection increases with the increase of the steric hindrance of the substituents and the best result (65percent e.e.) was obtained with the benzyl-substituted catalyst.A comparison of these results with those obtained with complexes derived from 2-amino-1-indanols gives useful information about the requirements for the optimization of the catalyst design.
