Methane, trifluoro(methylsulfonyl)- is a chemical compound with the molecular formula CF3SO2CH4. It is a colorless, odorless gas that is primarily used as a solvent in various chemical reactions and industrial processes. It is also used as a refrigerant and as a precursor in the production of various fluorinated compounds. Methane, trifluoro(methylsulfonyl)- is considered to be a stable and non-reactive compound under normal conditions, and it is not known to pose any significant health hazards to humans. However, it is important to handle this chemical with care and follow proper safety protocols when using it in industrial or laboratory settings.
Check Digit Verification of cas no
The CAS Registry Mumber 421-82-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 421-82:
(5*4)+(4*2)+(3*1)+(2*8)+(1*2)=49
49 % 10 = 9
So 421-82-9 is a valid CAS Registry Number.

Improved synthesis of trifluoromethyl sulfones used as intermediates for the preparation of di- or tri-substituted olefins
Eugene, Fabrice,Langlois, Bernard,Laurent, Eliane
, p. 301 - 310 (2007/10/02)
Primary and secondary trifluoromethyl sulfones (triflones) are efficiently obtained from easily available sodium trifluoromethanesulfinate (triflinate) and alkyl bromides in N,N-dimethylacetamide.This technique is more powerful than the potassium triflinate/acetonitrile system.Ethyl aconitate can be also produced in one step from ethyl bromoacetate and diisopropylethylamine, sodium triflinate being a catalyst.
