18-Fluor-9-octadecinsaeure, also known as ω-Fluorstearolsaeure, is a synthetic chemical compound that features a fluorine atom at the 18th carbon position in a long-chain fatty acid structure. 18-Fluor-9-octadecinsaeure (ω-Fluorstearolsaeure) is a derivative of stearic acid, an 18-carbon saturated fatty acid commonly found in animal and vegetable fats. The introduction of a fluorine atom at the ω (omega) position, which is the end of the carbon chain farthest from the carboxyl group, can significantly alter the chemical and physical properties of the molecule. 18-Fluor-9-octadecinsaeure is of interest in various fields, including materials science, where it may be used to create novel materials with unique properties, and in medical research, potentially for imaging or as a tracer in diagnostic procedures. The fluorine atom can enhance the compound's stability and reactivity, making it a subject of study for its potential applications in these areas.
The CAS Registry Mumber 1554-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 4 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1554-89: (6*1)+(5*5)+(4*5)+(3*4)+(2*8)+(1*9)=88 88 % 10 = 8 So 1554-89-8 is a valid CAS Registry Number.
