Direct Black 155 is a synthetic azo dye primarily utilized in the textile industry for dyeing cellulose-based fabrics such as cotton and rayon. It is categorized as a direct dye, allowing for its direct application to fabrics without the requirement of a mordant. Characterized by its deep black color, Direct Black 155 is widely used in the production of black clothing and textiles. Despite its applications, it has raised environmental and health concerns, particularly regarding wastewater pollution and potential skin irritations, prompting the search for more sustainable and eco-friendly dye alternatives.

Uses
Used in Textile Industry:Direct Black 155 is used as a dyeing agent for cellulose-based fabrics such as cotton and rayon, providing them with a deep black color. Its direct dye category allows for easy application without the need for a mordant, making the dyeing process more efficient and cost-effective. However, the industry's reliance on Direct Black 155 has led to increased scrutiny due to its environmental and health implications, including wastewater pollution and potential skin irritations. This has spurred interest in developing more sustainable and eco-friendly alternatives to synthetic dyes like Direct Black 155.
Check Digit Verification of cas no
The CAS Registry Mumber 71902-06-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,0 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.Calculate Digit Verification of CAS Registry Number 71902-06:
(7*7)+(6*1)+(5*9)+(4*0)+(3*2)+(2*0)+(1*6)=112
112 % 10 = 2
So 71902-06-2 is a valid CAS Registry Number.
