219659-52-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219659-52-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,6,5 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 219659-52:
(8*2)+(7*1)+(6*9)+(5*6)+(4*5)+(3*9)+(2*5)+(1*2)=166
166 % 10 = 6
So 219659-52-6 is a valid CAS Registry Number.

Asymmetric oxidation of dithioacetals and dithioketals catalyzed by a chiral vanadium complex
Bolm, Garsten,Bienewald, Frank
, p. 1327 - 1328 (1998)
Vanadium-catalyzed enantioselective oxidations of dithioacetals and dithioketals with 30% aqueous H2O2 give the corresponding monosulfoxides with enantioselectivities of up to 85% ee. The scope of this asymmetric catalysis has been i
