(1S,4S,5R)-4-Allyl-2-oxa-bicyclo[3.2.1]octan-3-one is a complex organic compound with a unique molecular structure. It is a chiral molecule, meaning it has a non-superimposable mirror image, and it is characterized by its specific stereochemistry, with the 1, 4, and 5 positions being in the S (left-handed) and R (right-handed) configurations, respectively. This bicyclic ketone features a three-membered ring fused to a six-membered ring, with an oxygen atom in the six-membered ring, hence the "2-oxa" descriptor. The allyl group attached to the 4-position and the ketone group at the 3-position are key functional groups that define its chemical properties. (1S,4S,5R)-4-Allyl-2-oxa-bicyclo[3.2.1]octan-3-one is of interest in organic chemistry and may have applications in the synthesis of various pharmaceuticals and fragrances due to its structural complexity and potential reactivity.
The CAS Registry Mumber 69556-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,5 and 6 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 69556-35: (7*6)+(6*9)+(5*5)+(4*5)+(3*6)+(2*3)+(1*5)=170 170 % 10 = 0 So 69556-35-0 is a valid CAS Registry Number.
