Urea, (2-chlorocyclohexyl)-, also known as 1-(2-chlorophenyl)-3-cyclohexylurea or linuron, is a widely used herbicide belonging to the phenylurea class. It is an off-white crystalline solid with the chemical formula C13H17ClN2O. Linuron is effective in controlling a broad spectrum of annual and perennial grasses and some broadleaf weeds in various crops, such as vegetables, fruits, and ornamental plants. It works by inhibiting photosynthesis in plants, leading to their death. The chemical is selective, meaning it targets specific weeds without harming the desired crop. However, it is essential to follow proper application guidelines to minimize potential risks to non-target plants, soil, and water resources.
The CAS Registry Mumber 64226-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,2,2 and 6 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 64226-81: (7*6)+(6*4)+(5*2)+(4*2)+(3*6)+(2*8)+(1*1)=119 119 % 10 = 9 So 64226-81-9 is a valid CAS Registry Number.
