Essigsaeure-<β,β-dichlor-phenethylester>, also known as 2,2-dichlorovinyl diethyl phosphate or DDVP, is an organophosphorus compound primarily used as an insecticide. It is a colorless, oily liquid with a pungent odor and is derived from the esterification of dichlorvos, a synthetic organophosphate insecticide. DDVP is effective against a wide range of insects, including flies, mosquitoes, and cockroaches, and is often used in household and agricultural settings. However, due to its high toxicity and potential health risks, its use has been restricted or banned in many countries. It is important to handle DDVP with caution and follow proper safety guidelines to minimize exposure and environmental impact.
The CAS Registry Mumber 1133-15-9 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, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1133-15: (6*1)+(5*1)+(4*3)+(3*3)+(2*1)+(1*5)=39 39 % 10 = 9 So 1133-15-9 is a valid CAS Registry Number.
