124658-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124658-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,5 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 124658-21:
(8*1)+(7*2)+(6*4)+(5*6)+(4*5)+(3*8)+(2*2)+(1*1)=125
125 % 10 = 5
So 124658-21-5 is a valid CAS Registry Number.

N-FLUORO-O-BENZENEDISULFONIMIDE: A USEFUL NEW FLUORINATING REAGENT

Davis, Franklin A.,Han, Wei

, p. 1631 - 1634 (1991)

N-Fluoro-o-benzenedisulfonimide (5) is a stable, easily prepared, highly efficient source of "electrophilic" fluorine which fluorinates enolates, azaenolates and carbanions in good to excellent yields.

Synthesis of 2-fluoro- acids, esters, and amides from α-dicyanoepoxides

Amanetoullah, A. Ould,Chaabouni,Baklouti

, p. 1155 - 1161 (2007/10/03)

The opening of α-dicyanoepoxides by pyridine polyhydrofluoride yields polymerisable 2-fluorocyanoformyls which may be kept intact when diluated in dichloromethane or ether. These intermediates react with nucleophiles such as water, methanol or amines to give respectively 2-fluoroacids, esters or amides.

Acide 2-fluoro-2-phenyl propanoique: preparation et utilisation comme agent chiral de derivation

Hamman, S.

, p. 225 - 232 (2007/10/02)

The enantiomers of 2-fluoro-2-phenyl propanoic acid have been separated and their absolute configurations determined: the specific rotation of the acid with an R configuration is 20D= -28.5 deg (c=1.5, ethanol).This acid has been
