70343-08-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70343-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,3,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 70343-08:
(7*7)+(6*0)+(5*3)+(4*4)+(3*3)+(2*0)+(1*8)=97
97 % 10 = 7
So 70343-08-7 is a valid CAS Registry Number.

The Rearragement of Aromatic Nitro Compounds. Part 1. The Reactions of Nitroanilines in Aqueous Sulphuric Acid

Murphy, J. Timothy,Ridd, John H.

, p. 1767 - 1772 (2007/10/02)

A number of substituted 2-nitroanilines rearange in concentrated sulphuric acid at 110 deg C to yield products that appear to be derived from 1,3-migration of the 2-nitro-group.For 2,3-dinitroaniline, the rate of reaction is almost independent of acidity over the range 83-97percent sulphuric acid and the solvent isotope effect k(H2SO4)/k(D2SO4) is 1.3-1.9.Methyl and t-butyl groups, when present as additional substituents in 2,3-dinitroaniline, have only a small effect on the reaction rate but 3-methyl-2-nitroaniline reacts much more slowly than 2,3-dinitroaniline.These results are discussed in terms of a rate-determining migration of the 2-nitro group following protonation at the 2-position.
