Check Digit Verification of cas no

The CAS Registry Mumber 745075-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,5,0,7 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 745075-90:
(8*7)+(7*4)+(6*5)+(5*0)+(4*7)+(3*5)+(2*9)+(1*0)=175
175 % 10 = 5
So 745075-90-5 is a valid CAS Registry Number.

Synthesis and evaluation of new chiral nonracemic C2-symmetric and unsymmetric 2,2′-bipyridyl ligands

Lyle, Michael P.A.,Draper, Neil D.,Wilson, Peter D.

, p. 877 - 885 (2007/10/03)

The synthesis of a series of chiral nonracemic and C2-symmetric 2,2′-bipyridyl ligands (R = Me, i-Pr and Ph) as well as the syntheses of the corresponding unsymmetric 2,2′-bipyridyl ligands (R = Me and Ph) is described. These bipyridyl ligands

A new class of chiral P,N-ligands and their application in palladium-catalyzed asymmetric allylic substitution reactions

Lyle, Michael P. A.,Narine, Arun A.,Wilson, Peter D.

, p. 5060 - 5064 (2007/10/03)

An efficient and modular synthesis of a series of chiral nonracemic P,N-ligands is reported. The P,N-ligands were prepared from 2-chloro-4-methyl-6, 7-dihydro-5H-[1]pyrindine-7-one and a series of substituted chiral C 2-symmetric 1,2-ethanediol
