Phosphonic acid, 1-heptynyl-, diethyl ester, also known as (1E)-1-hepten-1-ylphosphonic acid diethyl ester, is an organic compound with the chemical formula C11H23O3P. It is a colorless liquid with a molecular weight of 240.27 g/mol. Phosphonic acid, 1-heptynyl-, diethyl ester is characterized by the presence of a heptynyl group (a seven-carbon alkene chain) attached to a phosphonic acid moiety, which is further esterified with two ethyl groups. It is used in various applications, including as a flame retardant, a chelating agent, and in the synthesis of other organic compounds. Due to its phosphorus content, it exhibits unique properties such as thermal stability and reactivity with metal ions, making it valuable in industrial and chemical processes.

Check Digit Verification of cas no

The CAS Registry Mumber 3450-64-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,5 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3450-64:
(6*3)+(5*4)+(4*5)+(3*0)+(2*6)+(1*4)=74
74 % 10 = 4
So 3450-64-4 is a valid CAS Registry Number.
