Check Digit Verification of cas no

The CAS Registry Mumber 67776-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,7 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67776-46:
(7*6)+(6*7)+(5*7)+(4*7)+(3*6)+(2*4)+(1*6)=179
179 % 10 = 9
So 67776-46-9 is a valid CAS Registry Number.

Characterization of polyfunctional alkoxysilanes using potassium ( K+) ionization of desorbed species mass spectrometry

Michalczyk, Michael J.,Simonsick Jr., William J.,Sharp, Kenneth G.

, p. 261 - 266 (1996)

Potassium ionization of desorbed species (K+IDS) mass spectrometry has been used to characterize polyfunctional alkoxysilanes and the modes of reaction for 'star gel' precursors and simpler tetraalkoxysilanes. Efficient observation of molecular ions enabled by K+IDS can readily establish the purity of molecules such as Si(CH2CH2Si(OEt)3)4 and cyclo-(Me(CH2CH2Si(OEt)3)4SiO)4, and has been highly useful in determining the extent of intramolecular condensation in the star molecules. K+IDS has also established the distributions of polysilicate species and the presence of important reactive intermediates containing SiOOCH groups when Si(OMe)4 reacts with formic acid.

Preparation and characterization of nonpolar fluorinated carbosilane dendrimers by APcI mass spectrometry and small-angle X-ray scattering

Omotowa, Bamidele A.,Keefer, Keith D.,Kirchmeier, Robert L.,Shreeve, Jean'ne M.

, p. 11130 - 11138 (2007/10/03)

The following highly fluorinated nonpolar dendrimers were obtained in high yields from multiple hydrosilylation reactions between core hydride terminated carbosilane dendrimers and allyl-1,1-dihydrotrifluoroethyl ether or allyl-1,1-dihydroheptadecafluorononyl ether through divergent synthetic routes: Si[CH2-CH2SiMe2(CH2CH 2CH2OCH2CF3)]4 (7), Si{CH2CH2SiMe[CH2CH2SiMe(CH 2CH2CH2OCH2CF3) 2]2}4 (8), Si[CH2CH2Si(CH2CH2CH 2OCH2C8F17)3]4 (9), Si[CH2CH2SiMe2(CH2CH 2CH2OCH2C8F17)] 4 (10), and Si{CH2-CH2Si[CH2CH2Si(CH 2CH2CH2OCH2C8F 17)3]3}4 (11). These compounds were characterized by elemental and spectroscopic analyses. Valuable mass spectral data were obtained by using atmospheric pressure chemical ionization (APcI). The fluorinated dendrimer molecule and the nonfluorinated core scatter X-ray light differently and present unique slopes on the Guinier Plot of data from small-angle X-ray light scattering (SAXS) in hexafluorobenzene. Glass transition temperatures (Tg) and thermogravimetric analyses (TGA) of the dendrimers were determined.
