Check Digit Verification of cas no

The CAS Registry Mumber 2784-89-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2784-89:
(6*2)+(5*7)+(4*8)+(3*4)+(2*8)+(1*9)=116
116 % 10 = 6
So 2784-89-6 is a valid CAS Registry Number.

PARTIAL REDUCTION OF DINITROARENES TO NITROANILINES WITH HYDRAZINE HYDRATE.

Avyyangar,Kalkote,Lugade,Nikrad,Sharma

, p. 3159 - 3164 (2007/10/02)

Dinitroarenes containing substituents such as hydroxyl and amine groups could be conveniently reduced with 3 molar equivalents of hydrazine hydrate in presence of Raney nickel catalyst in ethanol/1,2-dichloro-ethane solvent mixture to give a product wherein one of the two nitro groups was reduced to the amino group. The yields of the partial reduction products are good. Under similar conditions alkoxyl substitutes in the o,p-position to the nitro groups were displaced by the hydrazine to give 2,4-dinitrophenyl-hydrazine as the main product. The details of the reduction reaction are described.

DERIVATIVES OF 4-AMINO-2-NITRODIPHENYLAMINE AS DYES FOR SYNTHETIC POLYMER FIBRES.

Peters. Arnold T.

, p. 131 - 134,132, 133 (2007/10/13)

Synthesis of a series of substituted 4-amino-2-nitrodiphenylamines is described. These compounds dye synthetic polymer fibres in bordeaux to violet-blue shades of moderate to poor light fastness. Light fastness properties are enhanced by the use of substituents which decrease the basicity of the 4-amino group; such substitution, however, results in color shifts into the yellow to orange region.
