It is a cyclic organic compound with a unique spiro structure, consisting of a dioxane ring fused to a dodecane chain. 1,4-Dioxaspiro[4.7]dodecane is commonly used as a solvent in the chemical industry, particularly in the formulation of specialty inks, adhesives, and coatings. It is also used as a fragrant ingredient in perfumes and personal care products. 1,4-Dioxaspiro[4.7]dodecane is flammable and may be harmful if inhaled, ingested, or absorbed through the skin, warranting careful handling and storage precautions. Additionally, it has been shown to have low acute toxicity in animal studies.
Check Digit Verification of cas no
The CAS Registry Mumber 183-03-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,8 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 183-03:
(5*1)+(4*8)+(3*3)+(2*0)+(1*3)=49
49 % 10 = 9
So 183-03-9 is a valid CAS Registry Number.

Evidence for an intramolecular transketalization equilibrium in a polyfunctional molecule is described.Using thermodynamic rules, it is possible to establish mathematical equations linking yields with relative ketalization energies and excess of reagent.Experiments with simple compounds are in good agreement with the results obtained from the mathematical model.Thus, for any bifunctional molecule, one can calculate the relative ketalization energy of each function from a simple experiment, and then determine the nature and the excess of the reagent which are necessary to realize the transketalization reaction in the best conditions of yield or selectivity.
