N-Picryl-p-phenylenediamine (NPPD) is a chemical compound with the formula C12H12N4O6. It is a derivative of p-phenylenediamine, where one of the hydrogen atoms is replaced by a picryl group (2,4,6-trinitrophenyl). NPPD is a yellow crystalline solid that is soluble in organic solvents and slightly soluble in water. It is primarily used as a stabilizer in rubber and latex products, where it helps to prevent degradation caused by heat, light, and oxygen exposure. NPPD is also known for its antioxidant properties and is used in the production of certain types of plastics and adhesives. Due to its potential health and environmental risks, its use is regulated in some regions.

Check Digit Verification of cas no

The CAS Registry Mumber 4197-62-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,9 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4197-62:
(6*4)+(5*1)+(4*9)+(3*7)+(2*6)+(1*2)=100
100 % 10 = 0
So 4197-62-0 is a valid CAS Registry Number.
