1-(1-Isopropyl-cyclohexyl)-ethan-1-on, also known as 1-(1-Methylethyl)cyclohexanecarboxaldehyde, is an organic compound with the molecular formula C10H18O. It is a colorless liquid with a strong, pungent odor and is used as a fragrance ingredient in various applications, such as perfumes, cosmetics, and household products. This aldehyde is derived from the cyclohexane ring structure, with an isopropyl group attached to one carbon and an ethanone group attached to another carbon. It is synthesized through various chemical reactions, including the condensation of cyclohexanone with acetone in the presence of a strong base. Due to its reactive nature, it is sensitive to air, light, and heat, and should be stored in a cool, dry place away from direct sunlight.
The CAS Registry Mumber 2903-33-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2903-33: (6*2)+(5*9)+(4*0)+(3*3)+(2*3)+(1*3)=75 75 % 10 = 5 So 2903-33-5 is a valid CAS Registry Number.
