Check Digit Verification of cas no

The CAS Registry Mumber 902779-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,7,7 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 902779-55:
(8*9)+(7*0)+(6*2)+(5*7)+(4*7)+(3*9)+(2*5)+(1*5)=189
189 % 10 = 9
So 902779-55-9 is a valid CAS Registry Number.

Titanium-salan-catalyzed asymmetric oxidation of sulfides and kinetic resolution of sulfoxides with H2O2 as the oxidant

Bryliakov, Konstantin P.,Talsi, Evgenii P.

, p. 3369 - 3376 (2008)

Asymmetric oxidation of sufides to sulfoxides by aqueous hydrogen peroxide with catalysis by titanium-salan complexes is presented. Optically active sulfoxides have been obtained with good to high enantioselectivities (up to 97% ee) by a tandem enantioselective oxidation and kinetic resolution procedure, the catalyst performing over 500 turnovers with no loss of enantioselectivity. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
