Trifluoro-methanesulfonic acid dichloro-fluoro-methyl ester, also known as CF3SO2ClCF2COOCHCl2, is a complex organic compound that belongs to the class of esters. It is characterized by its unique structure, which includes a trifluoromethyl group (CF3), a methanesulfonic acid moiety (SO2OH), and a dichlorofluoromethyl ester group (ClCF2COO). This chemical is highly reactive and is used in various chemical synthesis processes, particularly in the preparation of pharmaceuticals and agrochemicals. Due to its reactivity, it is essential to handle Trifluoro-methanesulfonic acid dichloro-fluoro-methyl ester with extreme care, following proper safety protocols to prevent potential hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 74501-97-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,0 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74501-97:
(7*7)+(6*4)+(5*5)+(4*0)+(3*1)+(2*9)+(1*7)=126
126 % 10 = 6
So 74501-97-6 is a valid CAS Registry Number.

Synthesis of Perfluoroalkyl Trifluoromethanesulfonates from Perfluoroalkyl Halides. Substitutive Electrophilic Dehalogenation with Chlorine(I) and Bromine(I) Trifluoromethanesulfonates

Katsuhara, Yutaka,DesMarteau, Darryl D.

, p. 2681 - 2686 (2007/10/02)

The reactions of chlorine(I) and bromine(I) trifluoromethanesulfonates with a variety of perfluoroalkyl halides are reported.The reactions form Br2, Cl2, or BrCl and the corresponding trifluoromethanesulfonate derivatives of the alkyls in good yields.Twelve new esters are reported and characterized.An SEi-type mechanism for the reactions is proposed with complete retention of configuration by the alkyl on substitution.
