439809-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 439809-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,8,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 439809-76:
(8*4)+(7*3)+(6*9)+(5*8)+(4*0)+(3*9)+(2*7)+(1*6)=194
194 % 10 = 4
So 439809-76-4 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.
