Description
C.I. Acid Red 158 is a red powder dye that is soluble in water and slightly soluble in ethanol, resulting in an orange color. It is a strong sulfuric acid dye that produces a cherry red color, which can be diluted to orange. The water solution of C.I. Acid Red 158 is orange, and it exhibits good light fastness, soaping fastness, and perspiration fastness. However, it has moderate fastness to oxygen bleaching and seawater, and it may cause staining.Uses
Used in Textile Industry:C.I. Acid Red 158 is used as a dye for wool, silk, and their blended fabrics for dyeing and printing. It provides good colorfastness properties, making it suitable for various textile applications.

4Check Digit Verification of cas no
The CAS Registry Mumber 8004-55-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 8004-55:
(6*8)+(5*0)+(4*0)+(3*4)+(2*5)+(1*5)=75
75 % 10 = 5
So 8004-55-5 is a valid CAS Registry Number.
