2,4-Dichlor-5-methyl-6-(α-methyl-allyl)-phenol, also known as dicamba, is a synthetic auxin-type herbicide widely used in agriculture to control broadleaf weeds and woody plants. It is a white crystalline solid with a chemical formula of C10H10Cl2O. Dicamba works by mimicking the action of plant hormones, causing uncontrolled growth and ultimately leading to the death of the targeted weeds. It is commonly applied as a post-emergence herbicide, either alone or in combination with other herbicides, to control weeds in various crops such as soybeans, cotton, and corn. Due to its effectiveness and low toxicity to humans and animals, dicamba has become a popular choice among farmers. However, its use has also raised concerns about potential environmental impacts, such as drift to non-target plants and the development of herbicide-resistant weeds.
The CAS Registry Mumber 1133-24-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 3 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1133-24: (6*1)+(5*1)+(4*3)+(3*3)+(2*2)+(1*4)=40 40 % 10 = 0 So 1133-24-0 is a valid CAS Registry Number.
