20317-19-5 Usage
Uses
Used in Textile Industry:
Reactive Yellow 17 is used as a dye for cotton, viscose, and silk fabrics. It is particularly suitable for dyeing and printing applications due to its ability to produce a vibrant red light yellow color. The dye is also fit for discharge printing, a technique that involves removing the dye from the fabric to create a pattern or design.
Standard:
Reactive Yellow 17 meets the following standards in terms of light fastness, oxygen bleaching, perspiration fastness, and soaping:
1. Light Fastness: ISO 5-6
2. Oxygen Bleaching: 4-5
3. Perspiration Fastness: 5
4. Soaping: 5
These standards indicate the dye's performance in terms of color stability and resistance to fading under various conditions, such as exposure to light, oxygen, sweat, and washing with soap. The higher the rating, the better the dye's performance in maintaining its color and resisting fading.
Preparation
2-(4-Amino-2,5-dimethoxyphenylsulfonyl)ethyl hydrogen sulfate diazo, and 4-(3-Methyl-5-oxo-4,5-dihydropyrazol-1-yl)benzenesulfonic acid coupling.

Check Digit Verification of cas no
The CAS Registry Mumber 20317-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,1 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20317-19:
(7*2)+(6*0)+(5*3)+(4*1)+(3*7)+(2*1)+(1*9)=65
65 % 10 = 5
So 20317-19-5 is a valid CAS Registry Number.
