648-36-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 648-36-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 648-36:
(5*6)+(4*4)+(3*8)+(2*3)+(1*6)=82
82 % 10 = 2
So 648-36-2 is a valid CAS Registry Number.

REACTION OF HYDROXY AND CARBONYL COMPOUNDS WITH SULFUR TETRAFLUORIDE. VIII. THE REACTIONS OF ALIPHATIC α-DIKETONES WITH SF4

Burmakov, A. I.,Stepanov, I. V.,Kunshenko, B. V.,Sedova, L. N.,Alekseeva, L. A.,Yagupol'skii, L. M.

, p. 1009 - 1013 (2007/10/02)

Aliphatic α-diketones react with sulfur tetrafluoride in anhydrous hydrogen fluoride to give the corresponding tetrafluoroalkanes.In addition to 2,2,3,3-tetrafluorobutane, the reaction of butanedione with SF4 in the presence of catalytic amounts of HF yields 2,3-difluorobutyleneglycol-2,3-orthosulfite and fluoro-substituted ethers.Butanedione homologs yield tetrafluoro derivatives and fluoroolefins.
