General Description
Acid black 209 is a water-soluble dye that is commonly used in the textile industry for coloring leather, cotton, and silk. It is known for its deep black color, good fastness and ability to dye fibers without the need for a mordant. The chemical structure of Acid black 209 consists of azo dyes, which are characterized by the presence of one or more azo groups (-N=N-) in their molecule. This dye is typically used in a dye bath with an acidic pH, which enhances its dyeing properties. However, it is important to use Acid black 209 with caution as it is considered harmful if ingested and may cause irritation to the skin and eyes upon contact. Therefore, proper safety precautions should be taken when handling this chemical.Check Digit Verification of cas no
The CAS Registry Mumber 72827-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,2 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.Calculate Digit Verification of CAS Registry Number 72827-68:
(7*7)+(6*2)+(5*8)+(4*2)+(3*7)+(2*6)+(1*8)=150
150 % 10 = 0
So 72827-68-0 is a valid CAS Registry Number.
