Check Digit Verification of cas no

The CAS Registry Mumber 406-93-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 406-93:
(5*4)+(4*0)+(3*6)+(2*9)+(1*3)=59
59 % 10 = 9
So 406-93-9 is a valid CAS Registry Number.

Direct C(sp3)?H Trifluoromethylation of Unactivated Alkanes Enabled by Multifunctional Trifluoromethyl Copper Complexes

Choi, Geunho,Lee, Geun Seok,Park, Beomsoon,Kim, Dongwook,Hong, Soon Hyeok

supporting information, p. 5467 - 5474 (2021/01/20)

A mild and operationally simple C(sp3)?H trifluoromethylation method was developed for unactivated alkanes by utilizing a bench-stable CuIII complex, bpyCu(CF3)3, as the initiator of the visible-light photoinduced reaction, the source of a trifluoromethyl radical as a hydrogen atom transfer reagent, and the source of a trifluoromethyl anion for functionalization. The reaction was initiated by the generation of reactive electrophilic carbon-centered CF3 radical through photoinduced homolytic cleavage of bpyCu(CF3)3, followed by hydrogen abstraction from an unactivated C(sp3)?H bond. Comprehensive mechanistic investigations based on a combination of experimental and computational methods suggested that C?CF3 bond formation was enabled by radical–polar crossover and ionic coupling between the resulting carbocation intermediate and the anionic CF3 source. The methylene-selective reaction can be applied to the direct, late-stage trifluoromethylation of natural products and bioactive molecules.

Process for preparing fluorinated acids

-

Page/Page column 3, (2008/06/13)

A process for the preparation a fluorinated acid of the formula RfCOOH, wherein the process includes the step of contacting: (i) a fluorinated alcohol of the formula RfCH2OH; and (ii) periodic acid; wherein each Rf is independently selected from linear, branched or cyclic hydrocarbyl of 1-12 carbon atoms having 1-25 fluorine atoms and any range there between; and wherein the contacting step is carried out in the presence of a catalyst and optionally in a reaction medium, at a temperature and length of time sufficient to produce the fluorinated acid.
