1-Hydroxy-perinaphthenyl-(1)-radical, also known as 1-hydroxy-1'-perinaphthenyl radical, is a complex organic molecule with a unique structure. It consists of a naphthalene core with a hydroxyl group (-OH) attached to one of the carbon atoms and a perinaphthenyl radical (a naphthalene derivative with a radical center) attached to the adjacent carbon atom. This molecule is characterized by its stability, reactivity, and potential applications in various chemical and industrial processes. Due to its specific structure, it can participate in various chemical reactions, such as oxidation, reduction, and radical reactions, making it an interesting subject for research in the field of organic chemistry.
The CAS Registry Mumber 2143-65-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 3 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2143-65: (6*2)+(5*1)+(4*4)+(3*3)+(2*6)+(1*5)=59 59 % 10 = 9 So 2143-65-9 is a valid CAS Registry Number.
