6408-31-7 Usage
Uses
Used in Textile Industry:
ACID RED 183 is used as a dye for the wool dyeing process due to its ability to produce a strong and lasting color. Its light fastness, soaping fastness, and perspiration fastness make it a suitable choice for textiles that require durability and resistance to fading.
Used in Leather Industry:
ACID RED 183 is also used in the leather coloring process, where its strong color and fastness properties are essential for creating visually appealing and long-lasting leather products. The dye's resistance to oxygen bleaching and fading in seawater makes it an ideal choice for leather items that may be exposed to various environmental conditions.
Standard:
The fastness properties of ACID RED 183 are measured according to ISO and AATCC standards, which provide a benchmark for the dye's performance in various conditions. The ISO standard rates the dye's light fastness at 7, soaping at 3-4, perspiration fastness at 4, and fastness to seawater at 2. The AATCC standard rates the dye's fading at 6-7, staining at 2, and fastness to oxygen bleaching at 5.
Preparation

Check Digit Verification of cas no
The CAS Registry Mumber 6408-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6408-31:
(6*6)+(5*4)+(4*0)+(3*8)+(2*3)+(1*1)=87
87 % 10 = 7
So 6408-31-7 is a valid CAS Registry Number.
