Urea, N'-[1-(3,4-dichlorophenyl)-1-methylethyl]-N-ethyl-N-(2-methylphenyl)-, also known as Diuron, is a widely used herbicide belonging to the chemical class of phenylureas. It is a white crystalline solid with the molecular formula C13H16Cl2N2O, and it is effective in controlling a broad spectrum of weeds, particularly in agricultural and non-crop areas. Diuron works by inhibiting photosynthesis in plants, leading to their death. It is known for its persistence in the environment and potential to contaminate water sources, which has led to concerns about its ecological impact. Despite these concerns, Diuron remains an important tool in weed management due to its effectiveness and relatively low mammalian toxicity.
The CAS Registry Mumber 64795-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,9 and 5 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 64795-60: (7*6)+(6*4)+(5*7)+(4*9)+(3*5)+(2*6)+(1*0)=164 164 % 10 = 4 So 64795-60-4 is a valid CAS Registry Number.
