Check Digit Verification of cas no

The CAS Registry Mumber 117559-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,5 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117559-89:
(8*1)+(7*1)+(6*7)+(5*5)+(4*5)+(3*9)+(2*8)+(1*9)=154
154 % 10 = 4
So 117559-89-4 is a valid CAS Registry Number.

Efficient protocol for the SO2F2-mediated deoxyfluorination of aliphatic alcohols

Epifanov, Maxim,Lai, Joey,Lee, Cayo,Sammis, Glenn M.,Wang, Cindy Xinyun

supporting information, (2021/09/28)

Alkyl fluorides are prevalent in both the pharmaceutical and agrochemical industries. As such, there has been significant interest over the past 40 years in the development of new synthetic methods to access these important fluorinated motifs. Herein we report the sulfuryl fluoride-mediated deoxyfluorination of alcohols using room temperature reaction conditions in only an hour. A wide range of primary aliphatic alcohols were efficiently converted to the corresponding fluoride in 46-70% isolated yields. Secondary alcohols were also effectively deoxyfluorinated in 50–92% yields. Chiral secondary alcohols were cleanly converted to the corresponding alkyl fluoride with only a minor deterioration of the enantioenrichment. A steroid derivative also underwent deoxyfluorination in 50% yield and 5.9:1 dr, with the major product resulting from net inversion of the stereocenter.

Rapid Deoxyfluorination of Alcohols with N-Tosyl-4-chlorobenzenesulfonimidoyl Fluoride (SulfoxFluor) at Room Temperature

Guo, Junkai,Kuang, Cuiwen,Rong, Jian,Li, Lingchun,Ni, Chuanfa,Hu, Jinbo

supporting information, p. 7259 - 7264 (2019/05/10)

The deoxyfluorination of alcohols is a fundamentally important approach to access alkyl fluorides, and thus the development of shelf-stable, easy-to-handle, fluorine-economical, and highly selective deoxyfluorination reagents is highly desired. This work describes the development of a crystalline compound, N-tosyl-4-chlorobenzenesulfonimidoyl fluoride (SulfoxFluor), as a novel deoxyfluorination reagent that possesses all of the aforementioned merits, which is rare in the arena of deoxyfluorination. Endowed by the multi-dimensional modulating ability of the sulfonimidoyl group, SulfoxFluor is superior to 2-pyridinesulfonyl fluoride (PyFluor) in fluorination rate, and is also superior to perfluorobutanesulfonyl fluoride (PBSF) in fluorine-economy. Its reaction with alcohols not only tolerates a wide range of functionalities including the more sterically hindered alcoholic hydroxyl groups, but also exhibits high fluorination/elimination selectivity. Because SulfoxFluor can be easily prepared from inexpensive materials and can be safely handled without special techniques, it promises to serve as a practical deoxyfluorination reagent for the synthesis of various alkyl fluorides.

Monofluoro analogs of eugenol methyl ether as novel attractants for the oriental fruit fly

Khrimian,DeMilo,Waters,Liquido,Nicholson

, p. 8034 - 8039 (2007/10/02)

Monofluoro analogs of eugenol methyl ether as potential attractants for the Oriental fruit fly (Bactrocera dorsalis, Hendel) were synthesized using selective fluorination reactions: electrophilic hydro- and iodofluorination, fluorodehydroxylation with (diethylamido)sulfur trifluoride (DAST), and Wittig fluoroolefination through the stabilized ylides. Unusual reduction of the double bond was detected in a reaction of eugenol methyl ether with pyridinium poly(hydrogen fluoride). Bis[(3,4-dimethoxyphenyl)alkyl] carbonates were identified as the novel nucleophilic substitution products of the intermediate generated from the reaction of 3,4-dimethoxybenzenealkanols with DAST. Reductive desulfonylation of fluorovinyl sulfone 24-(Z) with sodium amalgam afforded 1,2-dimethoxy-4-(3-fluoro-2-propenyl)benzene (E/Z = 85: 15) which was highly attractive to the Oriental fruit fly.
