59349-72-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 59349-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,3,4 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 59349-72:
(7*5)+(6*9)+(5*3)+(4*4)+(3*9)+(2*7)+(1*2)=163
163 % 10 = 3
So 59349-72-3 is a valid CAS Registry Number.

On the preparation of amine N-oxides by using dioxiranes

Ferrer, Marta,Sanchez-Baeza, Francisco,Messeguer, Angel

, p. 15877 - 15888 (2007/10/03)

The reaction of heterocyclic aromatic amines, anilines and tertiary amines with dimethyldioxirane (DMD) was examined. Treatment of heterocyclic aromatic amines and anilines with a slight excess of DMD at 0°C afforded the corresponding N-oxides in quantitative conversion yields. In addition, the oxidation was chemoselective in the presence of carbon-carbon double bonds. On the other hand, most of the tertiary amines assayed did afford also quantitative yields of the corresponding N. oxides, although reaction conditions, in particular regarding the amount of DMD required, depended on each substrate. Additional studies carried out on selected substrates suggested that certain N-oxides derived from tertiary amines deactivate DMD.
