1,3-Benzenediamine, 4-(2-pyridinylmethyl)-, also known as 4-(2-Pyridylmethyl)-1,3-phenylenediamine or PPD, is an organic compound with the chemical formula C11H12N4. It is a white to off-white crystalline solid that is widely used in the production of hair dyes, particularly for coloring hair black. PPD is known for its ability to penetrate the hair shaft and form a permanent color, making it a popular choice in the hair care industry. However, it is also known to cause allergic reactions in some individuals, and as a result, it is subject to strict regulations regarding its use and concentration levels in hair dye products.

63233-62-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63233-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,3 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.Calculate Digit Verification of CAS Registry Number 63233-62:
(7*6)+(6*3)+(5*2)+(4*3)+(3*3)+(2*6)+(1*2)=105
105 % 10 = 5
So 63233-62-5 is a valid CAS Registry Number.
