6709-58-6 Usage
Uses
Used in Textile Industry:
FAST DARK BLUE R SALT is used as a dye for cotton fabrics. It provides fastness properties to the fabric, ensuring that the color remains vibrant and resistant to various factors such as light, washing, and ironing.
FAST DARK BLUE R SALT offers the following fastness properties:
1. Fast light: The color remains stable and does not fade easily when exposed to sunlight or artificial light sources.
2. Soda boiling: The color is resistant to the effects of soda boiling, a process used to remove impurities from the fabric.
3. Oxygen bleaching: The color does not fade or change when exposed to oxygen bleach, a common treatment in the textile industry.
4. Ironing: The color remains stable and does not transfer to the iron when the fabric is ironed.
5. Chlorine bleaching: The color is resistant to chlorine bleach, a strong oxidizing agent used in the textile industry.
The fastness properties of FAST DARK BLUE R SALT are measured using various international standards, such as ISO and AATCC. The ratings for these properties range from 1/3N to 6, with higher numbers indicating better fastness. For example, the fastness to light is rated as 4, while the fastness to chlorine bleaching is rated as 3-4.

Check Digit Verification of cas no
The CAS Registry Mumber 6709-58-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,0 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6709-58:
(6*6)+(5*7)+(4*0)+(3*9)+(2*5)+(1*8)=116
116 % 10 = 6
So 6709-58-6 is a valid CAS Registry Number.
