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.
Copper electron-transfer induced trifluoromethylation with methyl fluorosulphonyldifluoroacetate
Chen, Qing-Yun,Yang, Guo-Ying,Wu Sheng-Wen
, p. 291 - 298 (2007/10/02)
Treatment of halogen compounds, RX, with methyl fluorosulfonyldifluoroacetate and copper powder in dimethylformamide for 4 h at 65 - 80 deg C resulted in the corresponding trifluoromethylated products, RCF3, in good yield.In the absence of halogen compounds and at 100 deg C, methyl triflone (CF3SO2CH3) was synthesized readily in the 20 - 30percent yield from the same reaction system.The fact that the reaction was suppressed by oxygen, p-dinitrobenzene or in the darkness suggested that a copper-induced electron-transfer process was involved in this new trifluoromethylating system.
