N,N'-Dichloro-N,N'-bis-(2,4-dichlorophenyl)-urea, also known as DCPMU, is a chemical compound with the molecular formula C13H8Cl6N2O. It is a derivative of urea, where two chlorine atoms are attached to the nitrogen atoms, and two 2,4-dichlorophenyl groups are connected to the remaining nitrogen atoms. N,N'-dichloro-N,N'-bis-(2,4-dichloro-phenyl)-urea is primarily used as a herbicide, specifically for controlling broadleaf and grassy weeds in various crops. DCPMU works by inhibiting the enzyme acetohydroxyacid synthase, which is essential for plant growth. It is known for its selective action and is used in agriculture to protect crops from weed competition, thus contributing to increased crop yields.
The CAS Registry Mumber 3893-00-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,9 and 3 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3893-00: (6*3)+(5*8)+(4*9)+(3*3)+(2*0)+(1*0)=103 103 % 10 = 3 So 3893-00-3 is a valid CAS Registry Number.
