166903-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 166903-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,9,0 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 166903-46:
(8*1)+(7*6)+(6*6)+(5*9)+(4*0)+(3*3)+(2*4)+(1*6)=154
154 % 10 = 4
So 166903-46-4 is a valid CAS Registry Number.

1-[Hydroxy(sulfonyloxy)iodo]-2,2,2-trifluoroethanes, CF3CH2I(OH)OSO2R: Stable, fluoroalkyl analogs of Koser's reagent

Zhdankin, Viktor V.,Kuehl, Chris J.,Simonsen, Angela J.

, p. 2203 - 2206 (2007/10/02)

1-[Hydroxy(sulfonyloxy)iodo]-2,2,2-trifluoroethanes [CF3CH2I(OH)OSO2R; R = CH3, CF3, p-CH3C6H4] can be prepared in two steps from trifluoroethyliodide by oxidation with pertrifluoroacetic acid and subsequent reaction with TsOH, MsOH, or Me3SiOTf. Reaction of the tosylate derivative 3 with silyl enol ethers affords α-tosyloxyketones, while triflate 5 smoothly reacts with trimethylsilylbenzene to give the respective trifluoroethyl(phenyl)iodonium triflate 8.
