Check Digit Verification of cas no

The CAS Registry Mumber 90472-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,7 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90472-61:
(7*9)+(6*0)+(5*4)+(4*7)+(3*2)+(2*6)+(1*1)=130
130 % 10 = 0
So 90472-61-0 is a valid CAS Registry Number.

Asymmetric Catalyses, 14. Enantioselective Hydrosilylation of Prochiral Ketones with Rh- and Pt-Complexes of Optically Active N-Chelate Ligands

Brunner, Henri,Reiter, Barbara,Riepl, Georg

, p. 1330 - 1354 (2007/10/02)

N-chelate ligands with a lateral chiral center, which derive from optically active primary amines, amino acids, and amino acid derivatives, catalyze in Rh and Pt complexes the enantioselective hydrosilylation of acetophenone, benzyl methyl ketone, and tert-butyl methyl ketone with diphenyl- and 1-naphthylphenylsilane.The ketones are transformed into the corresponding silyl ethers which on hydrolysis yield the alcohols 1-phenylethanol, 1-phenyl-2-propanol and 3,3-dimethyl-2-butanol. 37 N ligands 1 - 37 with 2 (I) and K (XX) as well as 21 isolated complexes II - XIX and XXI - XXIII are tested.The best optical inductions exceed considerably those which were obtained with optically active phosphane containing catalysts used up to now.
