Dichloralphenazone is a chemical compound belonging to the class of benzophenone derivatives, primarily used as a pre-emergent herbicide to control the growth of various annual grasses and broadleaf weeds in agricultural fields. It functions by inhibiting the synthesis of carotenoids, which are essential pigments for photosynthesis, ultimately leading to the death of the targeted plants. The chemical has a molecular formula of C13H8Cl2O3 and is characterized by its white crystalline appearance. Due to its effectiveness and low mammalian toxicity, dichloralphenazone is widely used in the management of crops such as corn, soybeans, and cotton. However, it is crucial to follow proper application guidelines to minimize potential environmental and health risks.
The CAS Registry Mumber 603-63-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 603-63: (5*6)+(4*0)+(3*3)+(2*6)+(1*3)=54 54 % 10 = 4 So 603-63-4 is a valid CAS Registry Number.
