Malathion β-Monoacid, also known as Malathion Monoacid or Malathion Acid, is a key intermediate in the synthesis of the widely used organophosphorus insecticide Malathion. It is a colorless to pale yellow liquid with a molecular formula of C10H19O6PS2 and a molecular weight of 330.35 g/mol. Malathion β-Monoacid is produced by hydrolyzing Malathion, which involves breaking down the ester bond to form the monoacid. Malathion β-Monoacid is used as a precursor in the manufacturing process of Malathion, which is effective against a broad spectrum of pests, including aphids, mites, and mosquitoes. It is important to note that while Malathion β-Monoacid is a chemical intermediate, it is not the final product used for pest control and requires further processing to become the active ingredient in Malathion-based insecticides.

1642-51-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1642-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1642-51:
(6*1)+(5*6)+(4*4)+(3*2)+(2*5)+(1*1)=69
69 % 10 = 9
So 1642-51-9 is a valid CAS Registry Number.
