Cyclononacosane is a cyclic alkane, a type of hydrocarbon with the molecular formula C29H58. It consists of 29 carbon atoms and 58 hydrogen atoms arranged in a closed ring structure. Cyclononacosane is a member of the cycloalkane family, which are cyclic versions of the linear alkanes. These cyclic compounds are known for their unique physical and chemical properties compared to their linear counterparts. Cyclononacosane, being a large cyclic molecule, has limited solubility in water and is more soluble in nonpolar solvents. It is not commonly found in nature but can be synthesized in a laboratory setting. Due to its size and structure, cyclononacosane has potential applications in materials science and as a precursor in the synthesis of more complex organic compounds.

297-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 297-33-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 297-33:
(5*2)+(4*9)+(3*7)+(2*3)+(1*3)=76
76 % 10 = 6
So 297-33-6 is a valid CAS Registry Number.
