57456-24-3 Usage
Uses
Used in Textile Industry:Vat blue 66 is used as a dyeing and printing pigment for textiles, particularly for denim and other cotton fabrics, due to its deep blue shade and excellent fastness properties. Its chemical stability and resistance to harsh conditions make it ideal for use in industrial environments.
Vat blue 66 is used as a pigment in the vat dyeing process for creating a permanent bond with the fabric. This process involves immersing the fabric in a vat of dye and reducing agents, ensuring the color's durability and resistance to fading.
Check Digit Verification of cas no
The CAS Registry Mumber 57456-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,5 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.Calculate Digit Verification of CAS Registry Number 57456-24:
(7*5)+(6*7)+(5*4)+(4*5)+(3*6)+(2*2)+(1*4)=143
143 % 10 = 3
So 57456-24-3 is a valid CAS Registry Number.
