β-(2,4-Dichlorphenyl)ethylaminoguanidin, also known as DCPA, is a chemical compound with the formula C9H11Cl2N5. It is a white crystalline solid that is used as a pre-emergent herbicide, primarily for controlling annual grasses and some broadleaf weeds in various crops. DCPA works by inhibiting cell division in germinating weed seeds, preventing their growth. It is widely used in agriculture, particularly in the cultivation of vegetables, fruits, and ornamental plants. Due to its potential environmental and health concerns, its use is regulated in many countries, and it is important to follow proper application guidelines to minimize risks.
The CAS Registry Mumber 46420-40-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,4,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 46420-40: (7*4)+(6*6)+(5*4)+(4*2)+(3*0)+(2*4)+(1*0)=100 100 % 10 = 0 So 46420-40-0 is a valid CAS Registry Number.
