619-18-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 619-18-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 619-18:
(5*6)+(4*1)+(3*9)+(2*1)+(1*8)=71
71 % 10 = 1
So 619-18-1 is a valid CAS Registry Number.

Steric-Hindrance-Induced Regio- and Chemoselective Oxidation of Aromatic Amines

Patil, Vilas Venunath,Shankarling, Ganapati Subray

, p. 7876 - 7883 (2015/09/01)

Unusual regio- and chemoselective oxidation of aromatic amines hindered with ortho substituents (except -NH2, -NHCH3, and -OH) to the corresponding nitro compounds is described by use of nonanebis(peroxoic acid). The mechanistic investigation for selective oxidation of amines ortho-substituted with -NH2 or -OH showed the involvement of H-bonding between the ortho hydrogen of the adjacent -XH group (where X = NH, NR, or O) and an oxygen atom from the diperoxy acid. Various mono- and diamines are oxidized into corresponding mononitro derivatives in high yield and purity without employing any protection strategies. The protocol was also found to successful on the gram scale.

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.

Water-soluble trisazo 8-amino-naphthol-1 dyes

-

, (2008/06/13)

Very effective direct dyeing of cotton and other hydroxyl- or nitrogen-containing fibers is effected with water-soluble triasazo dyes having the formula: where A is a radical of a diazoconstituent and A3 is a radical of a coupling constituent STR1 and A1 or A2 or both can have their azo linkages reversed. These dyes are very fast particularly to washing and to perspiration, and are so effective with cotton that dye baths for such use are rapidly exhausted and the disposal of used bath is less of a problem.
