The chemical compound "(1S,5R,6R,7R,15S)-7-(tetrahydro-2-pyranyloxy)-6-(E)-3-hydroxy-1-octenyl-2-oxabicyclo[3.3.0]octan-3-one" is a complex organic molecule with a unique structure. It features a bicyclic ring system with a three-carbon ring fused to a three-carbon ring, which is not fully saturated, indicated by the "2-oxa" part of the name, suggesting the presence of an oxygen atom in the ring. The compound has several chiral centers, as indicated by the "1S,5R,6R,7R,15S" prefixes, which describe the specific three-dimensional arrangement of atoms around these centers. It also contains a tetrahydro-2-pyranyloxy group, which is a type of protecting group often used in organic synthesis to mask hydroxyl groups, and an (E)-3-hydroxy-1-octenyl side chain, which adds to its complexity. This molecule is likely to be found in the field of natural products or as an intermediate in the synthesis of biologically active compounds due to its intricate structure and functional groups.
The CAS Registry Mumber 72243-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,4 and 3 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 72243-94: (7*7)+(6*2)+(5*2)+(4*4)+(3*3)+(2*9)+(1*4)=118 118 % 10 = 8 So 72243-94-8 is a valid CAS Registry Number.
