Phosphonoselenoic acid, ethyl-, O-ethyl ester, also known as ethyl phosphonoselenoate, is an organophosphorus compound with the chemical formula C4H9O3PSe. It is a colorless liquid that is soluble in organic solvents. Phosphonoselenoic acid, ethyl-, O-ethyl ester is characterized by the presence of a phosphonoselenoic acid group, which consists of a phosphorus atom bonded to a selenoic acid group and an ethyl group. Ethyl phosphonoselenoate is synthesized by the reaction of ethyl phosphonoselenoic acid with ethanol in the presence of a catalyst. It has potential applications in the synthesis of various organophosphorus compounds and as a reagent in chemical reactions. Due to its reactivity and potential toxicity, it is important to handle Phosphonoselenoic acid, ethyl-, O-ethyl ester with care and in accordance with proper safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 3958-00-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,5 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3958-00:
(6*3)+(5*9)+(4*5)+(3*8)+(2*0)+(1*0)=107
107 % 10 = 7
So 3958-00-7 is a valid CAS Registry Number.
