558-29-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 558-29-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 558-29:
(5*5)+(4*5)+(3*8)+(2*2)+(1*9)=82
82 % 10 = 2
So 558-29-2 is a valid CAS Registry Number.

Nucleophilic Iododifluoromethylation of Aldehydes Using Bromine/Iodine Exchange

Levin, Vitalij V.,Smirnov, Vladimir O.,Struchkova, Marina I.,Dilman, Alexander D.

, p. 9349 - 9353 (2015/09/28)

A method for the iododifluoromethylation of aromatic aldehydes using (bromodifluoromethyl)trimethylsilane (Me3SiCF2Br) is described. The selective formation of the CF2I group is based on using sodium iodide, with the sodium serving as a scavenger of bromide and iodide serving as a nucleophile with respect to difluorocarbene. The primary CF2I-addition products can undergo HI-elimination or iodine/zinc exchange followed by allylation in a one-pot manner.

IR LASER INDUCED DECOMPOSITION OF TRIFLUOROACETIC, PENTAFLUOROPROPIONIC AND HEPTAFLUOROBUTYRIC ANHYDRIDES

Kubat, Pavel,Pola, Josef

, p. 2460 - 2467 (2007/10/02)

The continuous-wave CO2 laser induced gas-phase decomposition of trifluoroacetic, pentafluoropropionic and heptafluorobutyric anhydride, sensitized by sulfur hexafluoride was studied in order to determine the course of the reactions in the absence of wall effects.The decompositions of all the compounds are assumed to involve cleavage of parent compound into acyl fluoride F(CF2)nCOF and .(CF2)nCO2. biradical, the latter undergoing decay into CO and F(CF2)n-1COF compounds.The theoretical treatment of the biradical by MNDO calculations as well as trapping withethene are presented.

CYCLOPROPANE CHEMISTRY. PART 5 . HEXAFLUOROCYCLOPROPANE AS A SOURCE OF DIFLUOROCARBENE

Birchall, J. Michael,Fields, Roy,Haszeldine, Robert N.,McLean, Reginald J.

, p. 487 - 496 (2007/10/02)

Thermolysis of hexafluorocyclopropane in the presence of ethylene, propene, vinyl chloride, and vinyl bromide gives good yields of the corresponding 1,1-difluorocyclopropanes, formed by addition of difluorocarbene to the olefin.The tetrafluoroethylene formed dimerises to octafluorocyclobutane, co-dimerises with the olefin, or survives, depending on the reaction conditions.With allene, hexafluorocyclopropane gives 1-(difluoromethylene)cyclopropane, 2,2,3,3-tetrafluorospiropentane, and products derived from tetrafluoroethylene and allene.
