General Description
The chemical 1,3,3-Trimethyl-2-[3-(1,3,3-trimethyl-2-indolinylidene)propenyl]-3H-indolium perchlorate, also known as NR, is a synthetic colorant commonly used in the textile and paper industries. It is a cationic dye that is often used to color fabrics, paper, and cosmetics. NR is known for its vibrant and stable color properties, making it a popular choice for a wide range of products. However, it has been subject to some controversy due to its potential environmental and health risks, particularly in regard to its toxicity and potential for bioaccumulation. As a result, there is ongoing research and debate about the safety and regulation of NR in various industries.Check Digit Verification of cas no
The CAS Registry Mumber 16021-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.Calculate Digit Verification of CAS Registry Number 16021-25:
(7*1)+(6*6)+(5*0)+(4*2)+(3*1)+(2*2)+(1*5)=63
63 % 10 = 3
So 16021-25-3 is a valid CAS Registry Number.
