6522-74-3 Usage
Uses
Used in Textile Industry:
Reactive Orange 1 is used as a dye for cotton, wool, silk, nylon, and viscose fiber yarns and fabrics. It is suitable for dyeing or disseminating, exhibiting high affinity. It is also used for direct and resist printing on viscose fabric.
Standard:
The light fastness, oxygen bleaching, perspiration fastness, and soaping of Reactive Orange 1 are rated as follows:
Light Fastness: ISO 4-5
Oxygen Bleaching: ISO 3
Perspiration Fastness: ISO 3-4
Soaping: ISO 4-5
Fading: ISO 3
Stain: ISO 3-4
Preparation
2-Aminobenzenesulfonic acid diazo, and 7-Amino-4-hydroxynaphthalene-2-sulfonic acid?coupling, and then again with 2,4,6-Trichloro-1,3,5-triazine?condensation.

Check Digit Verification of cas no
The CAS Registry Mumber 6522-74-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,2 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6522-74:
(6*6)+(5*5)+(4*2)+(3*2)+(2*7)+(1*4)=93
93 % 10 = 3
So 6522-74-3 is a valid CAS Registry Number.
