Check Digit Verification of cas no
The CAS Registry Mumber 202058-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,0,5 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 202058-33:
(8*2)+(7*0)+(6*2)+(5*0)+(4*5)+(3*8)+(2*3)+(1*3)=81
81 % 10 = 1
So 202058-33-1 is a valid CAS Registry Number.

Mn-salen catalyzed asymmetric oxidation of enol derivatives
Fukuda, Tsutomu,Katsuki, Tsutomu
, p. 4389 - 4392 (2007/10/03)
Mn-salen complex 1 was found to catalyze highly enantioselective oxidation of enol ethers with iodosylbenzene as a terminal oxidant giving the corresponding hydroxy acetals, when the reaction was carried out in an alcoholic solvent. The reactions in the u
