Check Digit Verification of cas no
The CAS Registry Mumber 198490-77-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,8,4,9 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 198490-77:
(8*1)+(7*9)+(6*8)+(5*4)+(4*9)+(3*0)+(2*7)+(1*7)=196
196 % 10 = 6
So 198490-77-6 is a valid CAS Registry Number.

Asymmetric thermal transformation, a new way to enantiopure biphenyl- bridged titanocene and zirconocene complexes: Efficient catalysts for asymmetric imine hydrogenation
Ringwald, Markus,Stürmer, Rainer,Brintzinger, Hans H.
, p. 1524 - 1527 (2007/10/03)
Enantiopure biphenyl-bridged titanocene and zirconocene complexes were obtained, by an asymmetric thermal transformation of the binaphthol complexes formed from the metallocene racemates and subsequent transformation to the corresponding dichlorides, in practically quantitative yields. Increased rates of this transformation in the presence of O2 gas or TEMPO indicate a radical reaction mechanism. The biphenyl-bridged titanocene enantiomers give rise to an efficient asymmetric catalysis for the hydrogenation of cyclic and noncyclic imines.
