10555-46-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10555-46-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,5,5 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10555-46:
(7*1)+(6*0)+(5*5)+(4*5)+(3*5)+(2*4)+(1*6)=81
81 % 10 = 1
So 10555-46-1 is a valid CAS Registry Number.

3-Methylenecyclobutyl, Cyclopent-3-enyl, and 3-Methylenecyclobutylmethyl Radicals; Absence of Homoallylic Conjugation

Walton, John C.

, p. 231 - 236 (2007/10/02)

The 3-methylenecyclobutyl radical and the cyclopent-3-enyl radicals show such small e.s.r. hyperfine splittings from the δ- and γ-hydrogens respectively that homoallylic conjugation can be ruled out.Semiempirical SCF-MO calculations indicated that the through-space interaction of the p-orbital at Cα with the ?-orbitals is negligible because they are >2 Angstroem apart.The 3-methylenecyclobutylmethyl radical rearranges by β-scission to give the 2-allylallyl radicals.The Arrhenius parameters of the rearrangement were determined by kinetic e.s.r. spectroscopy and by study of the reduction of 3-methylenecyclobutylmethyl bromide with tri-n-butyltin hydride.The resonance stabilisation of the rearranged radical causes no significant lowering of the activation energy for β-scission.
