782-90-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 782-90-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 782-90:
(5*7)+(4*8)+(3*2)+(2*9)+(1*0)=91
91 % 10 = 1
So 782-90-1 is a valid CAS Registry Number.

AN ABBREVIATED ROUTE TO DIFLUOROMALEIC ANHYDRIDE

Krespan, Carl G.

, p. 339 - 343 (1990)

Difluoromaleic anhydride is obtained in good yield by reaction of either hexafluoro-2,5-dihydrofuran or hexafluoro-2,5-dihydrothiophene with sulfur trioxide.Hexafluoro-2,5-dihydrothioyphene is prepared from sulfur and commercially available hexafluorocyclobutene, so its conversion to difluoromaleic anhydride in one step makes the latter readily available as well.
