Check Digit Verification of cas no
The CAS Registry Mumber 142453-19-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142453-19:
(8*1)+(7*4)+(6*2)+(5*4)+(4*5)+(3*3)+(2*1)+(1*9)=108
108 % 10 = 8
So 142453-19-8 is a valid CAS Registry Number.

Process for the preparation of difluoromaleic anhydride
-
, (2008/06/13)
A process for producing difluoromaleic anhydride by reacting sulfur trioxide with a fluorinated precursor selected from the group consisting of hexafluoro-2,5-dihydrofuran, hexafluoro-2,5-dihydrothiophene, difluoro-2,5-dihydrothiophene-2,5-dione and tetrafluoro-2,5-dihydrothiophene-2-one. Also disclosed are the compounds difluoro-2,5-dihydrothiophene-2,5-dione and tetrafluoro-2,5-dihydrothiophene-2-one. Difluoromaleic anhydride is useful for example as a component of fluoropolymers.
