213598-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 213598-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,5,9 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 213598-45:
(8*2)+(7*1)+(6*3)+(5*5)+(4*9)+(3*8)+(2*4)+(1*5)=139
139 % 10 = 9
So 213598-45-9 is a valid CAS Registry Number.

Oxidation of hydroxylamines to nitrones catalyzed by (salen)Mn(III) complexes. Enantioselective synthesis of a protected cis-dihydroxypyrroline N-oxide with Jacobsen catalyst

Cicchi, Stefano,Cardona, Francesca,Brandi, Alberto,Corsi, Massimo,Goti, Andrea

, p. 1989 - 1992 (1999)

Oxidation of N,N-disubstituted hydroxylamines to nitrones catalyzed by the Jacobsen catalyst occurs cleanly in the presence of hydrogen peroxide, sodium hypochlorite or iodosylbenzene as the stoichiometric oxidant. Meso 3,4-cis-isopropylidenedioxy-1-hydro

Synthesis of a new chiral pyrrolidine

Flores, Mari Fe,Nunez, Marta G.,Moro, Rosalina F.,Garrido, Narciso M.,Marcos, Isidro S.,Iglesias, Enrique F.,Garcia, Pilar,Diez, David

experimental part, p. 1501 - 1512 (2010/09/08)

The synthesis of a new chiral pyrrolidine has been performed using 2,3-O-isopropylidene-D-erythronolactol as a suitable starting material.

One-pot synthesis of cyclic nitrones and their conversion to pyrrolizidines: 7a-epi-crotanecine inhibits α-mannosidases

Cicchi,Marradi,Vogel,Goti

, p. 1614 - 1619 (2007/10/03)

A new straightforward and inexpensive one-pot procedure is described for the preparation of enantiopure five-membered cyclic nitrones starting from the corresponding lactols. Its efficiency relies on the condensation of unprotected hydroxylamine with read

TBAT-mediated nitrone formation of ω-mesyloxy-O-tert-butyldiphenylsilyloximes: Facile synthesis of cyclic nitrones from hemiacetals

Tamura, Osamu,Toyao, Atsushi,Ishibashi, Hiroyuki

, p. 1344 - 1346 (2007/10/03)

Chiral and cyclic nitrones were synthesized by TBAT-mediated desilylative cyclization of ω-mesyloxy-O-tert-butyl-diphenylsilyloximes, readily prepared from sugar derivatives by a consecutive treatment with O-tert-butyldiphenylsilylhydroxylamine and with m
