1-Oxaspiro[2.5]octa-5,7-dien-4-one, 5,6,8-trimethyl- is a complex organic compound with the molecular formula C11H16O2. It is a spiro compound, which means it contains a spiro atom (a central atom connected to three other carbon atoms), in this case, a carbon atom connected to three carbon atoms and one oxygen atom. The compound features a cyclohexane ring with a diene (two double bonds) and a carbonyl group (C=O). The 5,6,8-trimethyl substitution indicates that there are three methyl groups (CH3) attached to the carbon atoms at positions 5, 6, and 8. 1-Oxaspiro[2.5]octa-5,7-dien-4-one, 5,6,8-trimethyl- is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of more complex molecules or as a component in various chemical reactions.
The CAS Registry Mumber 78074-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,7 and 4 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 78074-82: (7*7)+(6*8)+(5*0)+(4*7)+(3*4)+(2*8)+(1*2)=155 155 % 10 = 5 So 78074-82-5 is a valid CAS Registry Number.
