357194-31-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 357194-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,1,9 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 357194-31:
(8*3)+(7*5)+(6*7)+(5*1)+(4*9)+(3*4)+(2*3)+(1*1)=161
161 % 10 = 1
So 357194-31-1 is a valid CAS Registry Number.

Tri- and tetrasubstituted α-fluorocyclohexanones with enantiomeric excesses in the range of 97-100%

Solladie-Cavallo, Arlette,Jierry, Loc,Bouerat, Laetitia,Taillasson, Philippe

, p. 883 - 891 (2007/10/03)

The α-fluorinated trisubstituted ketones (2S,5R)-(-)-7-Ia, (2R,5R)-(+)-7-IIe, (2S,5R)-(-)-8-Ia and (2R,5R)-(+)-8-IIe were synthesised from (+)-dihydrocarvone (99% (R)-configuration at C-5) and fully characterised. α-Fluorinated tetrasubstituted ketones (-)-9-Ia, (+)-9-Ia, (+)-9-IIa and (+)-10-Ia having e.e.s of ≥97% were synthesised as racemates from 3-methyl cyclo-hexenone then resolved into the pure enantiomers using chiral HPLC and fully characterised.
