Check Digit Verification of cas no

The CAS Registry Mumber 79628-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,6,2 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79628-13:
(7*7)+(6*9)+(5*6)+(4*2)+(3*8)+(2*1)+(1*3)=170
170 % 10 = 0
So 79628-13-0 is a valid CAS Registry Number.

Excited-State Behavior of Phenylethynyldisilanes: An Intramolecular Charge-Transfer Emission

Shizuka, Haruo,Okazaki, Katsuhiko,Tanaka, Hideaki,Tanaka, Masayuki,Ishikawa, Mitsuo,et. al

, p. 2057 - 2062 (2007/10/02)

Photochemical and photophysical properties of phenylethynyldisilanes in MP (methylcyclohexane/isopentane, 3:1 v/v) have been studied by means of picosecond and the nanosecond spectroscopy along with steady-state experiments.Intramolecular charge transfer in the excited singlet state of phenylethynyldisilanes occurs very rapidly (1(?,?*) state to the 1(2p?,3d?) CT state of the compounds is quite different from that of the usual TICT (twisted intramolecular charge transfer).Two decay components (fast and slaw) of the 1CT state are observed, which are ascribed to the intersystem crossing rates from 1CT to 3(?,?*), depending upon the molecular conformations of the 1CT state of phenylethynyldisilanes.The photochemical reaction to produce silacyclopropenes takes place efficiently via the 1CT state at room temperature, but not in MP glass at 77 K.

Photolysis of Organopolysilanes. Photochemical Behavior of Phenylethynyldisilanes

Ishikawa, Mitsuo,Sugisawa, Hiroshi,Fuchikami, Takamasa,Kumada, Makoto,Yamabe, Tokio,et al.

, p. 2872 - 2878 (2007/10/02)

The photolysis of phenylethynylpentamethyldisilane (1) afforded 1,1-dimethyl-2-phenyl-3-trimethylsilyl-1-silacyclopropene (8) and 1,1-dimethyl-3-phenyl-3-trimethylsilyl-1-silapropadiene.The absorption and emission spectra of 1 were measured at 300 and 77
