297-24-5

Cyclooctacosane, also known as octacosane or C28H58, is a cyclic alkane consisting of 28 carbon atoms arranged in a closed ring structure. It is a member of the alkane family, which are saturated hydrocarbons with the general formula CnH2n+2. Cyclooctacosane is a colorless, odorless, and non-polar liquid with a high boiling point due to its large molecular size and strong van der Waals forces. It is relatively unreactive and stable, making it suitable for various applications in the chemical industry, such as a solvent or a precursor for the synthesis of other compounds. However, due to its high molecular weight and potential environmental impact, cyclooctacosane is not commonly used in everyday applications.

297-24-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 297-24-5 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, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 297-24:
(5*2)+(4*9)+(3*7)+(2*2)+(1*4)=75
75 % 10 = 5
So 297-24-5 is a valid CAS Registry Number.
