Acetyl-(3-chloro-phenyl)-carbamic acid isopropyl ester, also known as chlorpropham, is a chemical compound with the formula C9H10ClNO2. It is a carbamate herbicide used to control the growth of weeds in various crops, including potatoes, sugar beets, and cereals. Chlorpropham works by inhibiting the production of auxins, which are essential for plant growth. It is effective against both annual and perennial weeds, and its selective nature allows it to be used without harming the crops. The chemical is typically applied as a pre-emergence treatment, and its effectiveness is attributed to its ability to be absorbed by the plant's roots and translocated to the growing points. Chlorpropham is known for its persistence in the soil, which can lead to potential environmental concerns, and as such, its use is regulated in many countries to minimize these risks.
The CAS Registry Mumber 5833-26-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,3 and 3 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5833-26: (6*5)+(5*8)+(4*3)+(3*3)+(2*2)+(1*6)=101 101 % 10 = 1 So 5833-26-1 is a valid CAS Registry Number.
