Check Digit Verification of cas no

The CAS Registry Mumber 196202-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,2,0 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 196202-01:
(8*1)+(7*9)+(6*6)+(5*2)+(4*0)+(3*2)+(2*0)+(1*1)=124
124 % 10 = 4
So 196202-01-4 is a valid CAS Registry Number.

PROCESS FOR PRODUCING 2-FLUORO-3-OXOALKYLCARBOXYLIC ACID ESTER

-

Page/Page column 6-8, (2008/06/13)

A process for producing a 2-fluoro-3-oxoalkylcarboxylic acid ester by fluorinating 3-oxoalkylcarboxylic acid ester with a fluorine gas is provided. The process is characterized in that the concentration of 3-oxoalkylcarboxylic acid ester in the reaction mixture for fluorination is maintained at 3wt% or higher. Also provided is a process for purifying 2-fluoro-3-oxoalkylcarboxylic acid ester characterized in that 2-fluoro-3-oxoalkylcarboxylic acid ester is produced at high yield and with less impurities by washing fluorinated 3-oxoalkylcarboxylic acid ester with 3 or more times as much water as the amount of reaction mixture. According to the processes of the present invention, not only is the generation of unwanted by-products minimized, but fluorinated 3-oxoalkylcarboxylic acid ester can be purified in an efficient manner. Thus, the present invention permits efficient production of considerably pure 2-fluoro-3-oxoalkylcarboxylic acid ester, a useful intermediate material in the production of various medical and agricultural agents.

Fluorination of methyl 3-oxopentanoate (MOP) using difluorobis(fluoroxy)methane, BDM

Bailey III, Wade H.,Casteel Jr., William J.,Syvret, Robert G.

, p. 1416 - 1420 (2007/10/03)

Difluorobis(fluoroxy)methane, BDM, is an electrophilic fluorinating agent that is capable of affecting selective monofluorination of 1,3-dicarbonyls such as diketones and ketoesters with very high regioselectivity. For example, in highly acidic anhydrous HF (AHF) solvent, fluorination of methyl 3-oxopentanoate (MOP) with BDM provides methyl 2-fluoro-3-oxopentanoate (MFOP) with 100% conversion and 95% selectivity. In mixtures of HF and methanol, fluorination conversions and selectivity are markedly lower. In comparison, direct fluorination of MOP with dilute F2 typically affords a fluorinated product that is less pure, being contaminated with radical fluorination byproducts that are difficult to separate. Fluorination of MOP with dilute mixtures of BDM and F2 is generally more selective than using dilute F2 alone.
