1324-58-9 Usage
Preparation
9-Ethyl-9H-carbazol-3-amine and 2,3,5,6-Tetrachlorocyclohexa-2,5 -diene-1,4-dione in Pyridine of condensation,with 99.5% of sulfuric acid sulfonation simultaneously closed and third (obtained Sirius Blue FTFGL); or in o-dichlorobenzene and 4-Methylbenzene-1-sulfonyl chloride condensation and cyclization as above and trisulfonated (obtained Sirius Blue FFRL), then into trisodium salt. Chemical structure of two products are the same.
Properties and Applications
bright blue. To black powder. Soluble in water solution for blue, insoluble in hydrochloric acid, sodium hydroxide solution and organic solvents. The strong sulfuric acid dyes for black solution, water-soluble poor. Dyeing of copper (a slight change in color, meet iron ion colored light yellow and dark. Reducing resistance, won’t be insurance powder reduction. Used for cotton, viscose, silk and their blended fabric dyeing, general is not used for printing. Usually used for washing the less number of flocking fabric.

Check Digit Verification of cas no
The CAS Registry Mumber 1324-58-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1324-58:
(6*1)+(5*3)+(4*2)+(3*4)+(2*5)+(1*8)=59
59 % 10 = 9
So 1324-58-9 is a valid CAS Registry Number.
