β-Pyronen, also known as 2-pyrone or 2H-pyran-2-one, is a heterocyclic organic compound characterized by a six-membered ring structure containing one oxygen atom and five carbon atoms. It serves as a key structural component in various natural products, such as flavonoids, chromones, and xanthones, and plays a significant role in the synthesis of pharmaceuticals, agrochemicals, and other bioactive compounds. Due to its versatile chemical properties, β-pyronen can undergo a range of reactions, including nucleophilic addition, electrophilic substitution, and cycloaddition, making it a valuable intermediate in organic synthesis.
The CAS Registry Mumber 24543-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,4 and 3 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 24543-41: (7*2)+(6*4)+(5*5)+(4*4)+(3*3)+(2*4)+(1*1)=97 97 % 10 = 7 So 24543-41-7 is a valid CAS Registry Number.
