C21H28O3 is an organic compound with a molecular formula indicating that it contains 21 carbon atoms, 28 hydrogen atoms, and 3 oxygen atoms. C21H28O3 falls under the category of terpenes, which are a large and diverse class of organic compounds derived from isoprene units. Terpenes are widely found in nature, particularly in plants, and are known for their diverse biological activities, including roles in plant defense and as precursors to essential oils. The specific compound C21H28O3 could be a derivative or a specific type of terpene, but without additional context or a more precise name, it's challenging to provide a detailed summary of its properties or functions. Terpenes are known for their complex structures and can vary greatly in their chemical and physical properties, making them a rich area of study in organic chemistry and natural product chemistry.
The CAS Registry Mumber 2429-44-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,2 and 9 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2429-44: (6*2)+(5*4)+(4*2)+(3*9)+(2*4)+(1*4)=79 79 % 10 = 9 So 2429-44-9 is a valid CAS Registry Number.
