2-Propynoic acid, 3-cyclopentyl-, also known as 3-cyclopentylpropiolic acid, is an organic compound characterized by a unique structure that combines a cyclopentyl group with a propynoic acid moiety. This molecule features a cyclopentyl ring, which is a five-membered carbon ring, attached to a propynoic acid group, which consists of a triple-bonded carbon (the propynyl group) and a carboxylic acid functional group. The compound is represented by the chemical formula C?H?O? and has a molecular weight of 132.15 g/mol. It is an important building block in organic synthesis, particularly for the creation of various pharmaceuticals and specialty chemicals, due to its reactive sites and the potential for further functionalization.
The CAS Registry Mumber 6053-88-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,5 and 3 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6053-88: (6*6)+(5*0)+(4*5)+(3*3)+(2*8)+(1*8)=89 89 % 10 = 9 So 6053-88-9 is a valid CAS Registry Number.
