169294-55-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 169294-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,2,9 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 169294-55:
(8*1)+(7*6)+(6*9)+(5*2)+(4*9)+(3*4)+(2*5)+(1*5)=177
177 % 10 = 7
So 169294-55-7 is a valid CAS Registry Number.

Hydroperoxide-mediated C-C bond formation: Synthesis of 1,2-dioxolanes from alkoxyhydroperoxides in the presence of Lewis acids

Dussault, Patrick H.,Zope, Umesh

, p. 3655 - 3658 (1995)

Lewis-acid activation of ozonolysis-derived hydroperoxyketals affords intermediate hydroperoxycarbenium ions (protonated carbonyl oxides) which undergo addition of allyltrimethylsilane to directly afford 1,2-dioxolanes.

A mild one-pot conversion of alkenes into amines through tandem ozonolysis and reductive amination

The effect of iodine on the peroxidation of carbonyl compounds

Zmitek, Katja,Zupan, Marko,Stavber, Stojan,Iskra, Jernej

, p. 6534 - 6540 (2008/02/10)

(Chemical Equation Presented) Peroxidation of ketones and aldehydes with iodine as a catalyst was studied. Ketones reacted with 30% aq hydrogen peroxide in the presence of 10 mol % of iodine to yield gem-dihydroperoxides in acetonitrile and hydroperoxyketals in methanol. The yield of hydroperoxidation of various cyclic ketones was 60-98%, including androstane-3,17-dione, while acyclic ketones were converted with a similar efficiency. Aromatic aldehydes were also converted to gem-dihydroperoxides with hydrogen peroxide and iodine as catalyst in acetonitrile and to hydroperoxyacetal in methanol, while the reactivity of aliphatic ones remained the same as in noncatalyzed reactions. tert-Butylhydroperoxide reacted in a similar manner, giving the corresponding perether derivatives. A study was also made of the relative kinetics of dihydroperoxidation from which the Hammet equation gave a reaction constant (ρ) of -2.76, indicating the strong positive charge development in the transition state and the important role of rehybridization in the conversion of hydroperoxyhemiketal to gem-dihydroperoxide. In acetonitrile, the iodine catalyst is apparently able to discriminate between the elimination of a hydroxy, methoxy, and hydroperoxy group and addition of water, methanol, and H2O2 to a carbonyl group.
