Description

ACID RED 88 is a deep red powder that is slightly soluble in acetone, soluble in ethanol, water, and soluble fiber element (red). It exhibits a blue-purple color when it meets strong sulfuric acid, and a yellow-brown precipitate when diluted. It is slightly soluble in nitric acid (red light yellow) and turns red-brown when it meets a sodium hydroxide solution, with a dark precipitate. It is also suitable for leather shading.

Uses

Used in Dye Industry:
ACID RED 88 is used as a dye for various applications due to its color properties and good discharge properties. It is particularly useful for dyeing copper and iron ions, where it provides a dark color and lustre.
Used in Leather Industry:
ACID RED 88 is used as a shading agent in the leather industry, where it provides a dark color and enhances the appearance of the leather.

Check Digit Verification of cas no

The CAS Registry Mumber 1658-56-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1658-56:
(6*1)+(5*6)+(4*5)+(3*8)+(2*5)+(1*6)=96
96 % 10 = 6
So 1658-56-6 is a valid CAS Registry Number.
