Urea, N-(1-cyanocyclohexyl)-N'-cyclohexyl-N-hydroxy-, also known as 3-(1-cyanocyclohexyl)-3-cyclohexyl-1,1-dimethylurea or linuron, is a widely used herbicide belonging to the substituted urea class. It 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. Linuron works by inhibiting photosynthesis in plants, leading to their death. It is characterized by its white crystalline appearance and has a molecular formula of C15H23N3O2. The chemical is known for its persistence in the environment and potential to leach into groundwater, which has led to concerns regarding its impact on aquatic ecosystems and human health.
The CAS Registry Mumber 66285-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,8 and 5 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 66285-90: (7*6)+(6*6)+(5*2)+(4*8)+(3*5)+(2*9)+(1*0)=153 153 % 10 = 3 So 66285-90-3 is a valid CAS Registry Number.
