Butyl-phenethyl-malonic acid, also known as BPMA, is a synthetic chemical compound with the molecular formula C17H22O4. It is a derivative of malonic acid, featuring a butyl group and a phenethyl group attached to the malonic acid backbone. BPMA is primarily used as a chiral building block in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of certain beta-lactam antibiotics and other complex organic molecules. Its unique structure allows for the creation of enantiomerically pure compounds, which is crucial in the development of drugs with specific therapeutic effects and reduced side effects. The compound is typically synthesized through a series of chemical reactions and is an important intermediate in the field of organic chemistry and medicinal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 4381-77-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,8 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4381-77:
(6*4)+(5*3)+(4*8)+(3*1)+(2*7)+(1*7)=95
95 % 10 = 5
So 4381-77-5 is a valid CAS Registry Number.
