The chemical compound "(+/-)-3c-(5-hydroxy-2r,3t,8,8-tetramethyl-4-oxo-3,4-dihydro-2H,8H-pyrano[2,3-f]chromen-6-yl)-3t-phenyl-acrylic acid" is a complex organic molecule with a unique structure. It features a pyrano[2,3-f]chromen-6-yl group, which is a type of flavonoid, attached to a phenyl-acrylic acid moiety. (+/-)-3c-(5-hydroxy-2r,3t,8,8-tetramethyl-4-oxo-3,4-dihydro-2H,8H-pyrano[2,3-f]chromen-6-yl)-3t-phenyl-acrylic acid is characterized by its 5-hydroxy, 2r,3t,8,8-tetramethyl, and 4-oxo groups, which contribute to its specific chemical properties. The presence of the 3c and 3t stereocenters indicates that it has chiral properties, meaning it can exist in both (+) and (-) forms, which are mirror images of each other. (+/-)-3c-(5-hydroxy-2r,3t,8,8-tetramethyl-4-oxo-3,4-dihydro-2H,8H-pyrano[2,3-f]chromen-6-yl)-3t-phenyl-acrylic acid is likely to be found in the realm of natural products or as a synthetic intermediate in the pharmaceutical or chemical industry, given its intricate structure and potential for biological activity.
The CAS Registry Mumber 477-23-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,7 and 7 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 477-23: (5*4)+(4*7)+(3*7)+(2*2)+(1*3)=76 76 % 10 = 6 So 477-23-6 is a valid CAS Registry Number.
