(+/-)-4c-phenyl-(3ar,9bc)-3a,9b-dihydro-4H-[1,3]dioxolo[4,5-c]chromen-2-one is a complex organic compound with a molecular structure that features a phenyl group attached to a chromen-2-one core. This core consists of a dihydro-4H-[1,3]dioxolo[4,5-c]chromene framework, which includes a dioxolane ring fused to a chromene system. The compound is characterized by its chiral centers at the 3a and 9b positions, which can exist in both R and S configurations, hence the (+/-) notation indicating a racemic mixture. The presence of these chiral centers contributes to the compound's stereochemistry and potential biological activity. (+/-)-4c-phenyl-(3ar,9bc)-3a,9b-dihydro-4H-[1,3]dioxolo[4,5-c]chromen-2-one is of interest in the field of organic chemistry, potentially for its pharmacological properties or as a synthetic intermediate in the preparation of more complex molecules.
The CAS Registry Mumber 1032-31-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,3 and 2 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1032-31: (6*1)+(5*0)+(4*3)+(3*2)+(2*3)+(1*1)=31 31 % 10 = 1 So 1032-31-1 is a valid CAS Registry Number.
