Urea, N-(2-hydroxy-4-nitrophenyl)-N'-(4-methoxyphenyl)-, also known as 4-Methoxy-2-nitrophenyl-N-phenylurea (MNPU), is a chemical compound with the molecular formula C14H13N3O4. It is a derivative of urea, featuring a 2-hydroxy-4-nitrophenyl group and a 4-methoxyphenyl group attached to the urea molecule. Urea, N-(2-hydroxy-4-nitrophenyl)-N'-(4-methoxyphenyl)- is often used as a photostabilizer in various applications, such as in the plastics and coatings industries, to protect materials from the harmful effects of ultraviolet (UV) radiation. MNPU works by absorbing UV light and dissipating the energy as heat, thus preventing the degradation of the material it is protecting. Due to its effectiveness and low toxicity, MNPU is a popular choice for stabilizing materials against UV-induced damage.

Check Digit Verification of cas no

The CAS Registry Mumber 92950-16-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,5 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92950-16:
(7*9)+(6*2)+(5*9)+(4*5)+(3*0)+(2*1)+(1*6)=148
148 % 10 = 8
So 92950-16-8 is a valid CAS Registry Number.
