Vat Yellow 49, also known as C.I. Vat Yellow 4, is a synthetic organic compound used as a dye in various applications, including textiles, plastics, and printing inks. It is characterized by its bright yellow color and high color strength. The chemical structure of Vat Yellow 49 consists of a benzanthrone-based chromophore, which provides its distinctive hue. This dye is known for its excellent lightfastness and heat resistance, making it suitable for use in high-performance applications. However, it is important to note that Vat Yellow 49, like other vat dyes, requires a specific process to fix the color onto substrates, typically involving a reduction step to convert the dye into a soluble leuco form, which can then be absorbed by the material and subsequently oxidized to regain its insoluble, colored form.

Check Digit Verification of cas no

The CAS Registry Mumber 57455-83-1 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 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57455-83:
(7*5)+(6*7)+(5*4)+(4*5)+(3*5)+(2*8)+(1*3)=151
151 % 10 = 1
So 57455-83-1 is a valid CAS Registry Number.
