Urea, N-[3-chloro-4-(4-chlorophenoxy)phenyl]-N'-(3,4-dichlorophenyl)- is a complex organic compound with the chemical formula C20H13Cl4N2O3. It is a derivative of urea, featuring a urea group (NH2-CO-NH2) connected to two distinct phenyl rings. One of these rings is substituted with a 3-chloro-4-(4-chlorophenoxy) group, while the other is substituted with a 3,4-dichlorophenyl group. Urea, N-[3-chloro-4-(4-chlorophenoxy)phenyl]-N'-(3,4-dichlorophenyl)- is known for its herbicidal properties, specifically as a selective pre-emergence and post-emergence herbicide used in agriculture to control a variety of broadleaf and grassy weeds. It works by inhibiting the synthesis of essential amino acids in plants, leading to their growth inhibition and eventual death. Due to its chemical structure and mode of action, it is an important tool in modern agriculture for managing weed populations and protecting crop yields.
The CAS Registry Mumber 14538-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,3 and 8 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 14538-36: (7*1)+(6*4)+(5*5)+(4*3)+(3*8)+(2*3)+(1*6)=104 104 % 10 = 4 So 14538-36-4 is a valid CAS Registry Number.
