Check Digit Verification of cas no
The CAS Registry Mumber 682-01-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 682-01:
(5*6)+(4*8)+(3*2)+(2*0)+(1*1)=69
69 % 10 = 9
So 682-01-9 is a valid CAS Registry Number.

Determination of Reactive Components in Silicone Foams

Analytical methods have been developed for the determination of reactive components used in the formulation of room temperature vulcanized (RTV) sislicone foams.The reactive components include total silanol (SiOH), silane hydrogen (SiH), tetrapropoxysilane (TPS), and diphenylmethylsilanol (DPMS).Total SiOH and SiH are determined by Fourier transform infrared (FTIR) spectrometry. the SiOH peak at 3687 cm-1 and the SIH peak at 2168 cm-1 were used for quantitation.The TPS content was determined by gas chromatography (GC), using a solid capillary open tubular (SCOT) column and linear programmed temperature control.The DPMS content was determined by gel permeation chromatography (GPC) using THF solvent.

Paragraph 0055; 0068; 0073, (2020/12/01)
An object of the present invention is to provide a method capable of producing a tetraalkoxysilane with a high energy efficiency and with a high yield. The present invention provides a method for producing a tetraalkoxysilane, the method including: a first step of reacting an alcohol with a silicon oxide; and a second step of bringing a vaporized component of the reaction mixture obtained in the first step into contact with a molecular sieve.

A new simple and efficient process for synthesizing tetraalkoxysilanes (TROS) directly from silica and alcohols was developed using molecular sieves as dehydrating agents. Using this method, a variety of TROS (R = ethoxy, n-propoxy, or n-butoxy) were obtained over 70% yields within 6 h. We also employed various natural silica sources in this process for practical applications.
