129575-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129575-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,7 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129575-55:
(8*1)+(7*2)+(6*9)+(5*5)+(4*7)+(3*5)+(2*5)+(1*5)=159
159 % 10 = 9
So 129575-55-9 is a valid CAS Registry Number.

Matrix isolation infrared and density functional theoretical studies of organic silanones, (CH3O)2Si=O and (C6H5)2Si=O

Khabashesku, Valery N.,Kerzina, Zoya A.,Kudin, Konstantin N.,Nefedov, Oleg M.

, p. 45 - 59 (2007/10/03)

Transient organic silanones (CH3O)2Si=O (3) and (C6H5)2Si=O (4) were generated by vacuum pyrolysis from 3,3-dimethoxy-6-oxa-3-silabicyclo[3.1.0]hexane (6) and its 3,3-diphenyl derivative (7), respectively, and after being trapped in argon cryogenic matrices at 12 K directly studied by IR spectroscopy. Vibrational assignments in the observed IR spectra of 3 and 4 have been made by comparison with the density functional theory B3LYP/6-311G(d, p) calculated harmonic frequencies and infrared intensities for these molecules and for the other silanones, H2Si=O (1), (CH3)2Si=O (2), and CH3(CH3O)Si=O (5), studied earlier by matrix isolation techniques. The observed bands at 1247 cm-1 in 3 and at 1205 cm-1 in 4 were assigned to the Si=O stretching modes, which under the influence of the same substituents show the similar frequency shifts as ν (M=O) in ketones, phosphinoxides, and sulfoxides. Under the conditions of vacuum pyrolysis studied the diphenylsilanone 4 was found to be more thermodynamically stable than the dimethoxy derivative 3, while the latter indicated a higher kinetic stability towards cyclooligomerization than the silanones 2 and 4.

Unstable methoxycyclosiloxanes n (n = 2,3): Thermal generation and direct mass spectral studies

Tamas, J.,Goemoery, A.,Besenyei, I.,Khabashesku, V. N.,Kerzina, Z. A.,et al.

, p. 147 - 152 (2007/10/02)

Direct evidence for formation of unstable methoxy cyclosiloxanes 2 (1) and 3 (2) in the gas phase has been obtained by a mass-spectral study of the vacuum pyrolysis of 3,3-dimethoxy-6-oxa-3-silabicyclohexane (4).Intermediates 1 and 2 have been detected in the mass spectra of the pyrolysis products of 4 as the corresponding molecular ions, and identified from their exact masses and compositions.The metastable transitions recorded by B/E scan show the fragmentation trends of 1, 2 and 4 under electron impact (70 eV).The ionization energies (IE), determined for 1 (8.81 +/- 0.1 eV) and 2 (8.50 +/- 0.1 eV) are considerably lower than the IE of linear methoxysubstituted silanes and alkenes.
