The chemical compound "(3aS)-3c-benzoyloxy-2c-benzoyloxymethyl-(3ar,9ac)-2,3,3a,9a-tetrahydro-furo[2',3':4,5]oxazolo[3,2-a]pyrimidin-6-one" is a complex organic molecule with a unique structure. It features a tetrahydro-furo[2',3':4,5]oxazolo[3,2-a]pyrimidin-6-one core, which is a type of fused heterocyclic ring system. The compound has two benzoyloxy groups, one at the 3c position and another at the 2c position, indicating the presence of benzoic acid ester groups. The stereochemistry is specified as (3aS) and (3ar,9ac), which describes the spatial arrangement of the atoms at these positions. (3aS)-3c-benzoyloxy-2c-benzoyloxymethyl-(3ar,9ac)-2,3,3a,9a-tetrahydro-furo[2',3':4,5]oxazolo[3,2-a]pyrimidin-6-one is likely to be of interest in medicinal chemistry or as a precursor in the synthesis of more complex molecules, given its intricate structure and potential for specific interactions with biological targets.
The CAS Registry Mumber 20289-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 20289-59: (7*2)+(6*0)+(5*2)+(4*8)+(3*9)+(2*5)+(1*9)=102 102 % 10 = 2 So 20289-59-2 is a valid CAS Registry Number.
