Calculate Digit Verification of CAS Registry Number 438051-20:
(8*4)+(7*3)+(6*8)+(5*0)+(4*5)+(3*1)+(2*2)+(1*0)=128
128 % 10 = 8
So 438051-20-8 is a valid CAS Registry Number.

Asymmetric transfer hydrogenation of ketones using amino alcohol and monotosylated diamine derivatives of indane

Palmer, Matthew J.,Kenny, Jennifer A.,Walsgrove, Tim,Kawamoto, Aparecida M.,Wills, Martin

, p. 416 - 427 (2007/10/03)

A series of 1,2-amino alcohol and 1,2-monotosylated diamine derivatives of indane have been applied as ligands in the asymmetric ruthenium(II)-catalysed transfer hydrogenation reaction of a series of ketones. Of these, the cis-1-aminoindan-2-ol derivative gives some of the highest asymmetric inductions reported for any amino alcohol ligand in this application.
