10134-35-7 Usage
Description
Disodium 5-bromo-2-[9-chloro-3-(sulphonatooxy)naphtho[1,2-b]thien-2-yl]-1H-indol-3-yl sulphate is a blue light grey to blue black powder that is soluble in water and organic solvents. Its aqueous solution is light yellow in color.
Uses
Used in Textile Industry:
Disodium 5-bromo-2-[9-chloro-3-(sulphonatooxy)naphtho[1,2-b]thien-2-yl]-1H-indol-3-yl sulphate is used as a dye for the printing of cotton fabric. It can be used for direct printing and discharge printing, with discharge printing being suitable for white discharge printing. It is also suitable for dyeing silk, wool, viscose, and acetate fiber fabrics, as well as polyester/cotton blended fabric printing.
Standard:
The dye has the following standards for various properties:
Ironing Fastness: ISO 4-5, AATCC 4
Chlorine bleach: ISO 5, AATCC 5
Light Fastness: ISO 6-7, AATCC 7
Mercerized: ISO 4-5, AATCC 4
Oxygen bleach: ISO 4, AATCC 4
Soaping: ISO 4-5, AATCC 4-5
Fading: ISO 4-5, AATCC 4

Check Digit Verification of cas no
The CAS Registry Mumber 10134-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,3 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10134-35:
(7*1)+(6*0)+(5*1)+(4*3)+(3*4)+(2*3)+(1*5)=47
47 % 10 = 7
So 10134-35-7 is a valid CAS Registry Number.
