166603-66-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 166603-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,6,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 166603-66:
(8*1)+(7*6)+(6*6)+(5*6)+(4*0)+(3*3)+(2*6)+(1*6)=143
143 % 10 = 3
So 166603-66-3 is a valid CAS Registry Number.

NMR spectra and crystal structure of a regioselective hydroformylation catalyst complex RhH(diphosphite)(CO)2

Rooy, Annemiek van,Kamer, Paul C. J.,Leeuwen, Piet W. N. M. van,Veldman, Nora,Spek, Anthony L.

, p. C15 - C18 (1995)

The crystal structure and characterization in solution are described for a very regioselective hydroformylation catalyst, RhH(CO)2(diphosphite) with as the diphosphite.The complex is formed under CO-H2 pressure from Rh(CO)2Acac and has a distorted TBP geometry with both phosphorus atoms in equatorial positions.Keywords: Rhodium; Diphosphite; Hydroformylation; Catalysis; Crystal structure
