197566-47-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197566-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,5,6 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 197566-47:
(8*1)+(7*9)+(6*7)+(5*5)+(4*6)+(3*6)+(2*4)+(1*7)=195
195 % 10 = 5
So 197566-47-5 is a valid CAS Registry Number.

Synthesis of trifluoro- or difluoromethylated olefins by regio- and stereocontrolled SN2′ reactions of gem-difluorinated vinyloxiranes

Ueki, Hisanori,Chiba, Takashi,Kitazume, Tomoya

, p. 3506 - 3511 (2006)

This paper presents a highly stereoselective synthesis of trifluoro- or difluoromethylated olefins via an SN2′ type fluorination or reductions of gem-difluorinated vinyloxiranes. Their fluorination with HF-Py furnished trifluoromethylated allyl

Ruthenium-catalyzed redox isomerization of trifluoromethylated allylic alcohols: Mechanistic evidence for an enantiospecific pathway

Bizet, Vincent,Pannecoucke, Xavier,Renaud, Jean-Luc,Cahard, Dominique

, p. 6467 - 6470 (2012/07/27)

Transfer news: A synthetic approach to chiral β-CF3- substituted saturated carbonyl compounds has been developed in which ruthenium complexes efficiently catalyze the redox isomerization of CF3-bearing allylic alcohols by an intramol
