2580-80-5 Usage
Description
Fast red RBE base is a chemical compound used in the textile industry, particularly for dyeing and printing on cotton fabrics. It is known for its fastness properties, which means that the color remains resistant to various factors such as light, washing, and other treatments.
Uses
Used in Textile Industry:
Fast red RBE base is used as a dye for cotton fabrics due to its excellent fastness properties. It provides good color yield and is resistant to light, soda boiling, oxygen bleaching, ironing, and chlorine bleaching. The fastness ratings for fast red RBE base according to ISO and AATCC standards are as follows:
Fast light: 4
Soda boiling: 5
Oxygen bleaching: 3-4
Ironing: 5
Chlorine bleaching: 5
These ratings indicate that fast red RBE base is a reliable and durable option for dyeing and printing on cotton fabrics, ensuring that the color remains vibrant and resistant to various treatments.

Check Digit Verification of cas no
The CAS Registry Mumber 2580-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2580-80:
(6*2)+(5*5)+(4*8)+(3*0)+(2*8)+(1*0)=85
85 % 10 = 5
So 2580-80-5 is a valid CAS Registry Number.
