Check Digit Verification of cas no

The CAS Registry Mumber 692-50-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 692-50:
(5*6)+(4*9)+(3*2)+(2*5)+(1*0)=82
82 % 10 = 2
So 692-50-2 is a valid CAS Registry Number.

Vicinal dichlorine elimination at dichloroalkenes promoted by a well-defined iron(0) complex

Thoreson, Kristen A.,McNeill, Kristopher

, p. 1646 - 1648 (2011)

Dechlorination reactions at sp2 C-Cl bonds by a pentaphosphino zero-valent iron (ZVI) complex are proposed to follow an oxidative addition, β-Cl-elimination pathway en route to iron-chloride, iron-hydride and iron-acetylide products, the distribution being dependent on the nature of alkyne produced.

PHOTOREACTIONS OF TETRAFLUORODIPHOSPHINE WITH ALKYNES

Morse, J. G.,Mielcarek, J. J.

, p. 41 - 50 (1988)

The reaction of tetrafluorodiphosphine with several alkynes in the gas phase and under UV irradiation were studied.Simple addition products were obtained in substantial yield from CF3CCH, CF3CCCH3 and CF3CCCF3.Methyl substituted alkynes gave little volatile product while ethyne and diphenyl ethyne gave no volatile addition products.Non-volatile byproducts were obtained, probably polymers, in substantial quantity in the latter instances.Volatile products were characterized by IR and NMR spectra and by mass spectrometry.

Page/Page column 19, (2021/09/11)

A method of producing (Z)-1,1,1,4,4,4-hexafluoro-2-butene (Z-1336mzz) is described. The method utilizes readily available halogenated starting materials, including 1,1,1-trichloro-2,2,2-trifluoroethane (CFC-113a) and carbon tetrachloride.

Method for preparing perfluoroalkadiene and perfluoroalkyne by gas-phase isomerization (by machine translation)

-

Paragraph 0044; 0045, (2020/06/05)

The invention relates to a method for preparing perfluorinated alkadiene and perfluorinated alkyne by gas phase isomerization. According to the method, perfluorinated cycloolefin is utilized as a rawmaterial, gas phase isomerization reaction happens under the existence of an isomerization catalyst to obtain the perfluorinated alkadiene and the perfluorinated alkyne. According to the method disclosed by the invention, the isomerization catalyst has cheap price; furthermore, the perfluorinated alkadiene or the perfluorinated alkyne can be synthesized at a high conversion rate and at a high selectivity by controlling a reaction temperature; the method is suitable for large-scale gas phase reaction to prepare the perfluorinated alkadiene and the perfluorinated alkyne and is especially suitable for large-scale gas phase reaction to prepare hexafluoro-1,3-butadiene and octafluoro-1,3-pentadiene.
