α,α'-Dichlor-3,4-xylenyl N-methylcarbamat, also known as aldicarb, is a synthetic organophosphorus compound widely used as an insecticide. It is a white crystalline solid with the chemical formula C9H11Cl2NO2. Aldicarb is highly toxic to both insects and mammals, acting as a potent acetylcholinesterase inhibitor, which disrupts the nervous system by preventing the breakdown of the neurotransmitter acetylcholine. This results in overstimulation and paralysis of the nervous system. Due to its high toxicity, aldicarb is classified as a Restricted Use Pesticide in many countries, and its use is limited to specific applications by trained professionals. It is also known for its systemic action, meaning it is absorbed by plants and can protect them from pests that feed on their sap. However, concerns about its potential to contaminate groundwater and its high toxicity have led to a decrease in its use and, in some cases, bans.
The CAS Registry Mumber 22134-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,3 and 4 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 22134-55: (7*2)+(6*2)+(5*1)+(4*3)+(3*4)+(2*5)+(1*5)=70 70 % 10 = 0 So 22134-55-0 is a valid CAS Registry Number.
