General Description
C.I. Direct Black 62 is a synthetic organic dye that is commonly used in the textile industry for coloring fabrics. It is classified as a direct dye, which means it has an affinity for cellulose fibers and can be applied directly to the fabric without the need for a mordant. C.I. Direct Black 62 is known for its deep black color and good color fastness, making it a popular choice for dyeing natural fibers such as cotton, rayon, and linen. However, like many synthetic dyes, there are concerns about its potential environmental and health impacts, so it is important to handle and dispose of it properly.Check Digit Verification of cas no
The CAS Registry Mumber 12221-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 12221-89:
(7*1)+(6*2)+(5*2)+(4*2)+(3*1)+(2*8)+(1*9)=65
65 % 10 = 5
So 12221-89-5 is a valid CAS Registry Number.
