Urea, N-(2,4-dichlorophenyl)-N'-(3,4-dichlorophenyl)-, also known as DCPMU, is a chemical compound with the molecular formula C13H8Cl4N2O. It is a derivative of urea, where two chlorophenyl groups are attached to the nitrogen atoms. DCPMU is primarily used as a herbicide, specifically targeting the inhibition of photosynthesis in plants by binding to the D1 protein of Photosystem II. This action disrupts the electron transport chain, leading to the death of the plant. The chemical is known for its effectiveness in controlling a wide range of broadleaf and grassy weeds in various agricultural settings. Due to its potential environmental and health impacts, the use of DCPMU is subject to strict regulations to ensure its safe application and minimize risks.
The CAS Registry Mumber 25417-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,1 and 7 respectively; the second part has 2 digits, 4 and 7 respectively. Calculate Digit Verification of CAS Registry Number 25417-47: (7*2)+(6*5)+(5*4)+(4*1)+(3*7)+(2*4)+(1*7)=104 104 % 10 = 4 So 25417-47-4 is a valid CAS Registry Number.
