50707-83-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50707-83-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 50707-83:
(7*5)+(6*0)+(5*7)+(4*0)+(3*7)+(2*8)+(1*3)=110
110 % 10 = 0
So 50707-83-0 is a valid CAS Registry Number.

Fungicidal activity of some o-nitrophenyl-hydrazones

Palomba,Pintore,Boatto,Asproni,Cerri,Pau,Farris

, p. 79 - 84 (2007/10/03)

The antimycotic activity of 16 o-nitrophenylhydrazones against strains of Hansenula anomala, Saccharomyces cerevisiae, Candida parapsylosis, and Cryptococcus albidus was tested. All 16 compounds inhibited growth of the yeast strains. The inhibitory activity of the 4 methyl-derivatives substituted on the aromatic nucleus was particularly significant.

Competitive Cyclisations of Singlet and Triplet Nitrenes. Part 8. The 1-(2-Nitrenophenyl)pyrazoles and Related Systems

Lindley, John M.,McRobbie, Ian M.,Meth-Cohn, Otto,Suschitzky, Hans

, p. 982 - 994 (2007/10/02)

The title nitrenes, derived by nitro-group deoxygenation with triethyl phosphite or by thermolysis or photolysis of the corresponding azide, have been studied.The effect of substituents (Cl, Br, OMe, NMe2, Me, CF3, and NO2) both meta and para to the nitrene has been examined as a determinant of the preferred mode of cyclisation to either a pyrazolobenzotriazole or a pyrazoloquinoxaline.Similarly, the role of solvents, sensitisers, and quenchers has been studied.Routes to the isomeric 1- and 2-(2-nitrophenyl)-4,5,6,7-tetrahydroindazoles have been defined and the literature corrected by studing the nitrene-mediated cyclisation of these products.The chemistry of the analogous 1-(2-carbenophenyl)- and the 1-(2-nitrenosulphonylphenyl)-3,5-dimethylpyrazoles has also been examined, the former giving 2-(3,5-dimethylpyrazol-1-yl)-benzaldazine and -benzyl alcohol while the latter gave products of intramolecular nitrene attack (a pyrazolobenzothiatriazine) and intermolecular reaction.Rationalisations for all the reaction pathways have been advanced.
