Check Digit Verification of cas no

The CAS Registry Mumber 163702-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,7,0 and 2 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 163702-08:
(8*1)+(7*6)+(6*3)+(5*7)+(4*0)+(3*2)+(2*0)+(1*8)=117
117 % 10 = 7
So 163702-08-7 is a valid CAS Registry Number.

New catalytic alkylation of in situ generated perfluoro-alkyloxy-anions and perfluoro-carbanions

Galimberti, Marco,Fontana, Giovanni,Resnati, Giuseppe,Navarrini, Walter

, p. 1578 - 1586 (2005)

Alkyl fluoroformates RHOC(O)F are a new family of excellent alkylating agents. Perfluoroacyl fluorides, selected perfluoroketones and fluoroolefins can be alkylated to hydrofluoroethers RF-O-R H and hydrofluoroalkanes RF-RH, respectively. Potassium fluoride and cesium fluorides catalysts in glymes at 50-100°C are the preferred experimental conditions.

Method for preparing fluorine-containing ether

-

Paragraph 0088-0089, (2019/07/29)

The invention relates to a 'method for preparing fluorine-containing ether', and belongs to the field of chemical synthesis. The method comprises the steps that under a nitrile solvent condition, carbonyl fluoride, trifluoroacetyl fluoride, pentafluoropropionyl fluoride, heptafluoro-n-butyryl fluoride, heptafluoro-iso-butyryl fluoride and other acyl fluorides are taken as raw materials to have anaddition reaction with metal fluorides to obtain perfluoroalkoxide, then under water catalysis, the perfluoroalkoxide and a low-toxic or even non-toxic harmless alkylating agent are subjected to an alkylation reaction to obtain the fluorine-containing ether. The method for preparing the fluorine-containing ether has the advantages that not only is the reaction condition mild, the yield of the fluorine-containing ether is high, but also the low-toxic or even non-toxic harmless alkylating agent is taken as a safe alkylation agent, the process is safe and reliable, and effective separation can beperformed by an ordinary distillation means in the industry.

Process for preparing hydrofluoroethers

Page 5, (2008/06/13)

Process for obtaining hydrofluoroethers of formula (I): A-(Rf)n0—CF(Rf1)—O—Rh??(I) wherein: n0 is zero or 1; Rf is a bivalent radical: C1-C20 (per)fluoroalkylene, optionally containing one or more oxygen atoms; —CFW′O—(Rf2)—CFW—, wherein W and W′, equal or different, are F, CF3; Rf2 is a (per)fluoropolyoxyalkylene; Rf1 is F or a C1-C10 (per)fluoroalkyl or (per)fluorooxyalkyl radical; Rh is a C1-C20 linear, branched, saturated or unsaturated alkyl, or C7-C20 alkylaryl, A═F, (Rh2O)—CF(Rf4)—, —C(O)F, wherein Rh2, equal to or different from Rh, has the Rh meanings and Rf4, equal to or different from Rf1, has the Rf1 meanings; wherein a mono- or bifunctional carbonyl compound of formula (IV): B—Rf—C(O)Rf1??(IV) B being F or —C(O)Rf4, Rf, Rf1 and Rf4 being as above, is reacted with at least one equivalent of a fluoroformate of formula (III) R—OC(O)F??(III) wherein R═Rh or Rh2 as above defined; in the presence of an ion fluoride compound (catalyst) and of a dipolar aprotic organic compound, liquid and inert under the reaction conditions.
