50990-39-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50990-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,9 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50990-39:
(7*5)+(6*0)+(5*9)+(4*9)+(3*0)+(2*3)+(1*9)=131
131 % 10 = 1
So 50990-39-1 is a valid CAS Registry Number.

Remarkable increase in the rate of the catalytic epoxidation of electron deficient styrenes through the addition of Sc(OTf)3 to the MnTMTACN catalyst

Nodzewska, Aneta,Watkinson, Michael

, p. 1461 - 1464 (2018)

The effect of Lewis acids on the catalytic activity of [Mn2(μ-O)3(TMTACN)2](PF6)2 in the epoxidation of styrenes using hydrogen peroxide as the oxidant has shown that the addition of Sc(OTf)3 at low catalytic loading results in a very significant increase in the efficiency of the catalyst and a reduction of the reaction time to only 3 minutes in most cases.

Chromium - Salen-mediated alkene epoxidation: A theoretical and experimental study indicates the importance of spin-surface crossing and the presence of a discrete intermediate

Brandt, Peter,Norrby, Per-Ola,Daly, Adrian M.,Gilheany, Declan G.

, p. 4299 - 4307 (2002)

The mechanism of alkene epoxidation by chromium(v) oxo salen complexes has been studied by DFT and experimental methods. The reaction is compared to the closely related Mn-catalyzed process in an attempt to understand the dramatic difference in selectivit
