Check Digit Verification of cas no

The CAS Registry Mumber 29086-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,0,8 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29086-41:
(7*2)+(6*9)+(5*0)+(4*8)+(3*6)+(2*4)+(1*1)=127
127 % 10 = 7
So 29086-41-7 is a valid CAS Registry Number.

REACTIONS 0F PROPELLANE

Zefirov, N. S.,Surmina, L. S.,Sadovaya, N. K.,Blokhin, A. V.,Tyurekhodzhayeva, M. A.,et al.

, p. 2002 - 2014 (2007/10/02)

The photochemical reactions of propellane with bromine, dioxane dibromide, iodine, (dichloroiodo)benzene, methyl iodide, carbon tetrabromide, bromoform, and tributyltin hydride take place by a radical mechanism and lead to the formation of the products from addition at the central bond, i.e., 1,3-substituted bicyclopentanes.In the photochemically initiated reactions of chloroform, carbon tetrachloride, and bromomalonic ester with propellane compounds with the structure of 1,1'-bis(bicyclopentane) are formed in significant amounts in addition to the above-mentioned compounds.The addition of hydrogen bromide with irradiation leads to the brominated derivatives of cyclopropane and cyclobutane.The formation of cyclobutane derivatives is also observed in the reactions with such reagents as bromine or dioxane bromide (with irradiation) and 2-nitrobenzenesulfenyl chloride (in the presence of atmospheric oxygen).In the course of the reaction of propellane with electrophilic reagents (mercuric acetate, tripropyl- and triallylboranes) ring cleavage occurs, and derivatives of methylenecyclobutane are formed.

The Spiropentyl Radical and Some Homolytic Reactions of Spiropentane

Kennedy, Alan J.,Walton, John C.,Ingold, Keith U.

, p. 751 - 757 (2007/10/02)

Spiropentyl radical was generated by Hydrogen abstraction from spiropentane by t-butoxyl radical and its e.s.r. spectrum obtained.The experimental e.s.r. parameters were compared with computational results obtained using semi-empirical SCF MO methods.The spiropentyl radicals do not undergo β-scission in the observable temperature range (T H2 attack by the halogen atom to give 1-(halogenomethyl)cyclopropylmethyl radicals.The β-scission of these latter radicals has been inves tigated by e.s.r. spectroscopy and by the reduction of 1,1-bisbromomethylcyclopropane with tri-n-butyltin hydride.
