Check Digit Verification of cas no

The CAS Registry Mumber 420133-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,3 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 420133-89:
(8*4)+(7*2)+(6*0)+(5*1)+(4*3)+(3*3)+(2*8)+(1*9)=97
97 % 10 = 7
So 420133-89-7 is a valid CAS Registry Number.

Synthesis of new chiral thiazoline-containing ligands

Abrunhosa, Isabelle,Gulea, Mihaela,Levillain, Jocelyne,Masson, Serge

, p. 2851 - 2859 (2007/10/03)

New chiral ligands, including bi- and tridentate thiazoline derivatives, analogues of known oxazolines, have been synthesized by a general and convenient procedure, starting from dithioesters and commercial enantiopure 2-aminoalcohols. A preliminary test shows the ability of such ligands to act as asymmetric catalysts in Pd-catalyzed allylic substitution reaction.
