((2S,3S,4S,5R,6R)-3-Acetoxy-4,5-bis-benzyloxy-6-benzyloxymethyl-tetrahydro-pyran-2-yl)-acetic acid ethyl ester is a complex organic compound with a molecular formula of C28H34O8. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the 2, 3, 4, 5, and 6 positions all having distinct configurations (S for 2, 3, 4 and R for 5, 6). The compound features a tetrahydro-pyran ring, which is a type of cyclic ether, and is functionalized with acetoxy, benzyloxy, and benzyloxymethyl groups. The acetic acid ethyl ester group indicates the presence of an ester linkage derived from acetic acid and ethanol. ((2S,3S,4S,5R,6R)-3-Acetoxy-4,5-bis-benzyloxy-6-benzyloxymethyl-tetrahydro-pyran-2-yl)-acetic acid ethyl ester is likely used in organic synthesis, particularly in the preparation of complex molecules or as an intermediate in pharmaceutical or chemical manufacturing processes. Its specific application would depend on the target molecule's structure and the synthetic route being employed.
The CAS Registry Mumber 89756-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,5 and 6 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 89756-04: (7*8)+(6*9)+(5*7)+(4*5)+(3*6)+(2*0)+(1*4)=187 187 % 10 = 7 So 89756-04-7 is a valid CAS Registry Number.
