321-33-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 321-33-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 321-33:
(5*3)+(4*2)+(3*1)+(2*3)+(1*3)=35
35 % 10 = 5
So 321-33-5 is a valid CAS Registry Number.

Wong, O. Andrea,Shi, Yian

supporting information; experimental part, p. 8377 - 8380 (2010/03/25)

(Chemical Equation Presented) The asymmetric epoxidation of various fluoroolefins has been studied using chiral ketone catalyst, and up to 93% ee was achieved with fructose-derived ketone 1.

Low-temperature 19F NMR spectroscopy of 1-fluoro-1-lithioethenes - Stability, shifts and unexpected coupling constants

Kvicala, Jaroslav,Hrabal, Richard,Czernek, Jiri,Bartosova, Ivana,Paleta, Oldrich,Pelter, Andrew

, p. 211 - 218 (2007/10/03)

Half-lives and fluorine atom shifts of stabilized 1-fluoro-l-lithioethenes bearing hydrogen, fluorine, phenyl, and/or dimethylphenylsilyl groups in the β-positions have been determined by a low-temperature 19F NMR spectroscopy. Some 1-fluoro-1-lithioethenes displayed an exceptionally low value of the trans-3JFF coupling constant. Stereoselectivity of carbenoid formation, as well as an effect of configuration on the stability is discussed.

Regio- and Stereoselective Synthesis of Fluorinated Enynes and Dienes via 1,1- or 1,2-Halofluoroalkenes

Eddarir, Said,Francesch, Charlette,Mestdagh, Helene,Rolando, Christian

, p. 741 - 756 (2007/10/03)

Monofluorinated enynes and dienes were synthesized stereospecifically through palladium-catalyzed condensation of 1-halo-1-fluoroalkenes or 1-halo-2-fluoroalkenes with monosubstituted alkynes or alkenes, or with allyltributyltin.The various halofluoroalke

Synthesis of fluorinated enynes via 1-bromo 1-fluoro alkenes

Eddarir, Said,Francesch, Charlette,Mestdagh, Helene,Rolando, Christian

, p. 4449 - 4452 (2007/10/02)

A stereospecific synthesis of fluorinated enynes was performed through palladium catalysed condensation of 1-bromo 1-fluoro 2-arylethylenes, synthetised from 1-carboxyl 1-fluoro 2-arylethylene with monosubstitued alkynes.
