20721-50-0 Usage
Description
DISPERSE BLACK 9 is a synthetic organic compound that serves as a dye in the textile industry, specifically designed for synthetic fibers such as polyester, nylon, and acetate. Its chemical structure enables it to disperse easily in water, making it suitable for dyeing fabrics with a high affinity for hydrophobic materials. Known for its deep, intense black color, it is commonly used in the production of dark-colored garments, upholstery, and other textiles. However, it requires careful handling due to potential harm if ingested, inhaled, or causing skin irritation.

Check Digit Verification of cas no
The CAS Registry Mumber 20721-50-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,2 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20721-50:
(7*2)+(6*0)+(5*7)+(4*2)+(3*1)+(2*5)+(1*0)=70
70 % 10 = 0
So 20721-50-0 is a valid CAS Registry Number.
