11099-79-9 Usage
General Description
Reactive Red 21 is a synthetic organic compound that belongs to the azo dye group. It is commonly used as a red dye in the textile industry to color cotton, wool, and silk. The chemical structure of Reactive Red 21 includes azo and amino groups, making it a water-soluble dye that can be easily absorbed by fibers. It is known for its good color fastness, meaning it is resistant to fading or running when exposed to water or light. However, Reactive Red 21 is also considered a hazardous chemical and may pose risks to human health and the environment if not handled and disposed of properly. Therefore, safe handling procedures and proper waste management are crucial when working with Reactive Red 21.Check Digit Verification of cas no
The CAS Registry Mumber 11099-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,0,9 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.Calculate Digit Verification of CAS Registry Number 11099-79:
(7*1)+(6*1)+(5*0)+(4*9)+(3*9)+(2*7)+(1*9)=99
99 % 10 = 9
So 11099-79-9 is a valid CAS Registry Number.
