α,ω-Diphenylpentadecan, also known as 1,15-diphenylpentadecane, is an organic compound with the molecular formula C27H34. It is a colorless, crystalline solid that belongs to the class of alkanes, specifically a diphenylalkane. The compound consists of a linear alkane chain with 15 carbon atoms (pentadecane) and two phenyl groups attached to the terminal carbon atoms (α and ω positions). α,ω-Diphenylpentadecan is used as a reference material in various analytical techniques, such as gas chromatography and mass spectrometry, due to its unique structure and properties. It is also employed as a standard for calibration purposes in the petrochemical industry and as a model compound for studying the behavior of long-chain alkanes.
The CAS Registry Mumber 24065-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,0,6 and 5 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 24065-61: (7*2)+(6*4)+(5*0)+(4*6)+(3*5)+(2*6)+(1*1)=90 90 % 10 = 0 So 24065-61-0 is a valid CAS Registry Number.
