Bicyclo[3.3.1]nonane is a cyclic alkane with the molecular formula C9H16. It consists of two fused cyclohexane rings with a quaternary carbon atom at the bridgehead position. This unique structure results in a highly strained molecule due to the presence of two adjacent quaternary carbons and a small ring angle, which makes it less stable compared to other cyclic alkanes. Bicyclo[3.3.1]nonane is an important intermediate in organic synthesis, particularly for the preparation of various natural products and pharmaceuticals, as it can be easily functionalized and transformed into more complex molecules. Its strained nature also makes it a subject of interest in the study of ring strain and conformational analysis in organic chemistry.

280-65-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 280-65-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 280-65:
(5*2)+(4*8)+(3*0)+(2*6)+(1*5)=59
59 % 10 = 9
So 280-65-9 is a valid CAS Registry Number.
