7,9-di-tert-butylspiro[4,5]dodeca-6,9-dien-8-one is a complex organic compound characterized by its unique molecular structure. It features a spiro ring system, which consists of two rings sharing a common atom, in this case, the 8-ketone carbon. The compound is further distinguished by the presence of two tert-butyl groups attached to the 7 and 9 positions of the spiro ring system. These bulky, non-polar groups contribute to the compound's steric hindrance and lipophilic properties. The diene component, indicated by the "dien" in the name, refers to the presence of two conjugated double bonds within the dodecadiene framework. This specific arrangement of functional groups and structural features endows 7,9-di-tert-butylspiro[4,5]dodeca-6,9-dien-8-one with distinct chemical and physical properties, making it a compound of interest in various chemical and industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 4290-37-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,9 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4290-37:
(6*4)+(5*2)+(4*9)+(3*0)+(2*3)+(1*7)=83
83 % 10 = 3
So 4290-37-3 is a valid CAS Registry Number.

ALKYLATION OF PHENOLS BY DIHALOGENOALKANES IN AN ALKALINE MEDIUM AS A METHOD FOR THE PRODUCTION OF SUBSTITUTED SPIRAN 2,5-CYCLOHEXADIEN-1-ONES

Krysin, A. P.

, p. 1079 - 1082 (2007/10/02)

The reaction of 2,6-di-tert-butylphenol with 1,4- and 1,5-dihalogenoalkanes in the presence of sodium hydroxide in THF at 130-150 deg C leads to the formation of substituted spiran 2,5-cyclohexadien-1-ones.The yields are higher when the dibromoalkanes are
