768-04-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 768-04-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 768-04:
(5*7)+(4*6)+(3*8)+(2*0)+(1*4)=87
87 % 10 = 7
So 768-04-7 is a valid CAS Registry Number.

Decarboxylative fluorination of β-Ketoacids with N-fluorobenzenesulfonimide (NFSI) for the synthesis of α-fluoroketones: Substrate scope and mechanistic investigation

Zhang, Rui,Ni, Chuanfa,He, Zhengbiao,Hu, Jinbo

, p. 166 - 172 (2017/09/18)

Cesium carbonate (Cs2CO3)-mediated decarboxylative fluorination of β-ketoacids using NFSI in the MeCN/H2O mixed solvent system affords α-fluoroketones with a broad scope. Both electron-rich and electron-deficient α-non-substituted β-ketoacids are amenable to this protocol. The mechanistic study indicates that the reaction proceeds through electrophilic fluorination followed by decarboxylation, which is different from the decarboxylative fluorination of normal carboxylic acids.

Synthesis of α-Fluoromethyl Ketones via Allene Epoxides

Kabat, Marek M.

, p. 435 - 440 (2007/10/02)

α-Fluoromethyl ketones are formed via the reaction of allene epoxides with tetrabutylammonium fluoride trihydrate (TBAF*3H2O) in THF.
