Description
Acid Blue 80 is a synthetic dye characterized by its blue color and red light blue powder form. It is soluble in water, but its solution may exhibit precipitation over time. The dye is known for its strong color in sulfuric acid, where it appears as red light blue, and green light blue when diluted. In nitric acid, it takes on a brown hue. Its water solution is deep blue, and it turns blue when hydrochloric acid or sodium hydroxide is added.
Uses
Used in Textile Industry:
Acid Blue 80 is used as a dye for various types of fabrics, including wool, silk, polyamide fiber, and their blended fabrics. It is particularly effective for dyeing scattered hair, tops, yarn packages, socks, and knitting yarn. The dye can also be used for direct printing on wool and silk fabrics.
Used in Leather Industry:
In addition to its applications in the textile industry, Acid Blue 80 is also utilized in leather dyeing, providing a vibrant blue color to the material.

Check Digit Verification of cas no
The CAS Registry Mumber 4474-24-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,7 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4474-24:
(6*4)+(5*4)+(4*7)+(3*4)+(2*2)+(1*4)=92
92 % 10 = 2
So 4474-24-2 is a valid CAS Registry Number.
