62013-44-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62013-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,0,1 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 62013-44:
(7*6)+(6*2)+(5*0)+(4*1)+(3*3)+(2*4)+(1*4)=79
79 % 10 = 9
So 62013-44-9 is a valid CAS Registry Number.

Inclusion complexes of EMPO derivatives with 2,6-di-O-methyl-β- cyclodextrin: Synthesis, NMR and EPR investigations for enhanced superoxide detection

Bardelang, David,Rockenbauer, Antal,Karoui, Hakim,Finet, Jean-Pierre,Biskupska, Inga,Banaszak, Karol,Tordo, Paul

, p. 2874 - 2882 (2008/02/08)

The free radical trapping properties of eight 5-alkoxycarbonyl-5-methyl-1- pyrroline N-oxide (EMPO) type nitrones and those of 5,5-dimethyl-1-pyrroline N-oxide (DMPO) were evaluated for trapping of superoxide anion radicals in the presence of 2,6-di-O-methyl-β-cyclodextrin (DM-β-CD). 1H-NMR titrations were performed to determine both stoichiometries and binding constants for the diamagnetic nitrone-DM-β-CD equilibria. EPR titrations were then performed and analyzed using a two-dimensional EPR simulation program affording 1: 1 and 1: 2 stoichiometries for the nitroxide spin adducts with DM-β-CD and the associated binding constants after spin trapping. The nitroxide spin adducts associate more strongly with DM-β-CD than the nitrones. The ability of the nitrones to trap superoxide, the enhancement of the EPR signal intensity and the supramolecular protection by DM-β-CD against sodium l-ascorbate reduction were evaluated.

CARBON-CARBON BOND FORMATION BY MEANS OF SUBSTITUTION AND ADDITION REACTIONS INVOLVING THE POLYMER-SUPPORTED CARBANION FROM METHYL NITROACETATE

Fiandanese, V.,Naso, F.,Scilimati, A.

, p. 1187 - 1190 (2007/10/02)

A polymer-supported carbanion has been prepared from methyl nitroacetate and reacted with alkyl halides or activated olefins to give α-nitroesters.
