130-20-1 Usage
Description
Vat Blue 6, also known as C.I. Vat Blue 6, is a vat dye characterized by its reddish shade and blue powder appearance. It is primarily used for dyeing cotton fabrics, offering a water solubility of up to 1.0% and a tinting strength of 100-105%.
Uses
Used in Textile Industry:
Vat Blue 6 is used as a dye for cotton fabrics, providing a vibrant reddish-blue color to the material. Its high tinting strength ensures a deep and long-lasting coloration.
Used in Environmental Applications:
Materials dyed with Vat Blue 6 exhibit enhanced adsorption of metals and nanoparticles, making them suitable for the preparation of materials used in wastewater cleanup. This property allows for the effective removal of pollutants from water sources, contributing to environmental sustainability.

Check Digit Verification of cas no
The CAS Registry Mumber 130-20-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130-20:
(5*1)+(4*3)+(3*0)+(2*2)+(1*0)=21
21 % 10 = 1
So 130-20-1 is a valid CAS Registry Number.
