(1S,4R,5S)-4-Isopropyl-8-methyl-9-oxo-spiro[4.5]dec-7-ene-1-carbonitrile is a complex organic compound with a unique molecular structure. It is characterized by a spiro[4.5]decane core, which is a fused ring system consisting of a cyclohexane and a cyclopentane ring. The compound features a carbonitrile group (-CN) at the 1-position, an isopropyl group (-CH(CH3)2) at the 4-position, and a methyl group (-CH3) at the 8-position. The 9-oxo group indicates the presence of a carbonyl functional group at the 9-position, which contributes to the compound's reactivity and properties. The stereochemistry of the molecule is defined by the (1S,4R,5S) configuration, which specifies the three-dimensional arrangement of the chiral centers at the 1st, 4th, and 5th positions. This specific arrangement of functional groups and stereochemistry gives the compound its distinct chemical and physical properties, making it a potentially interesting candidate for further study in various fields, such as pharmaceuticals or materials science.
The CAS Registry Mumber 74654-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,5 and 4 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 74654-54: (7*7)+(6*4)+(5*6)+(4*5)+(3*4)+(2*5)+(1*4)=149 149 % 10 = 9 So 74654-54-9 is a valid CAS Registry Number.
