51868-46-3 Usage
Description
Disperse Blue 291G is a synthetic dye primarily used in the textile industry for coloring various materials, such as polyester, nylon, and acrylic fibers. It is known for its high color strength, good lightfastness, and resistance to fading, making it a popular choice for a wide range of applications.
Uses
Used in Textile Industry:
Disperse Blue 291G is used as a coloring agent for synthetic fibers, such as polyester, nylon, and acrylic, due to its high color strength, good lightfastness, and resistance to fading. It provides vibrant and long-lasting color to textiles, enhancing their visual appeal and durability.
However, it is important to note that Disperse Blue 373, a similar dye, has been found to have adverse effects on the soil and water environment and is considered a major mutagen in the environmental system. This highlights the need for responsible and sustainable practices in the textile industry to minimize the environmental impact of dye usage.

Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 51868-46-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,6 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 51868-46:
(7*5)+(6*1)+(5*8)+(4*6)+(3*8)+(2*4)+(1*6)=143
143 % 10 = 3
So 51868-46-3 is a valid CAS Registry Number.
