α,α,α-Trichloromethanesulfenamide, also known as Chlorsulfuron, is a widely used herbicide belonging to the sulfonylurea class. It is an effective post-emergence herbicide that inhibits acetolactate synthase, a key enzyme in the biosynthesis of branched-chain amino acids in plants. This action leads to the cessation of plant growth and eventually causes plant death. Chlorsulfuron is particularly effective against broadleaf and grassy weeds in various crops, including cereals, sugarcane, and some fruit trees. It is known for its low use rates and long residual activity, making it a popular choice for weed control in agricultural settings. However, due to its persistence and potential for environmental impact, it is crucial to follow proper application guidelines to minimize risks to non-target organisms and the ecosystem.
The CAS Registry Mumber 39782-55-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,8 and 2 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 39782-55: (7*3)+(6*9)+(5*7)+(4*8)+(3*2)+(2*5)+(1*5)=163 163 % 10 = 3 So 39782-55-3 is a valid CAS Registry Number.
