Diphenoxy-malonic acid diethyl ester, also known as DPMA, is a chemical compound with the molecular formula C20H22O6. It is a synthetic analog of the naturally occurring plant alkaloid diphenoxylate, which is used as an anti-diarrheal agent. DPMA is a white crystalline solid that is soluble in organic solvents and has a molecular weight of 366.39 g/mol. It is primarily used in the pharmaceutical industry as an intermediate in the synthesis of various drugs, including anti-diarrheal medications. The compound is known for its potential to cause dependence and abuse, similar to its natural counterpart, and is therefore subject to regulatory controls in many countries.

4525-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4525-71-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,2 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 4525-71:
(6*4)+(5*5)+(4*2)+(3*5)+(2*7)+(1*1)=87
87 % 10 = 7
So 4525-71-7 is a valid CAS Registry Number.
