31353-78-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31353-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,3,5 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31353-78:
(7*3)+(6*1)+(5*3)+(4*5)+(3*3)+(2*7)+(1*8)=93
93 % 10 = 3
So 31353-78-3 is a valid CAS Registry Number.

Heme Protein Catalysts for Carbon-Silicon Bond Formation In Vitro and In Vivo

-

Paragraph 0257; 0258, (2017/08/26)

The present invention provides compositions and methods for catalyzing the formation of carbon-silicon bonds using heme proteins. In certain aspects, the present invention provides heme proteins, including variants and fragments thereof, that are capable of carrying out in vitro and in vivo carbene insertion reactions for the formation of carbon-silicon bonds. In other aspects, the present invention provides methods for producing an organosilicon product, the method comprising providing a silicon-containing reagent, a carbene precursor, and a heme protein; and combining the components under conditions sufficient to produce an organosilicon product. Host cells expressing the heme proteins are also provided by the present invention.

NOVEL SYNTHESIS METHOD OF SILANE COMPOUND FOR PACKAGING OPTICAL DEVICES

-

Paragraph 0097; 0101-0102, (2016/12/26)

The present invention relates to a novel synthesis method of a silane compound, and more specifically, to a method for manufacturing a silane compound with the amount of impurities minimized by using an Ullmann-type reaction instead of a conventional Girg

Polymerization of arylene bis-silanols

-

, (2008/06/13)

This invention is directed to the preparation of certain arylene bis-silanols in highly purified form and to the preparation of five new arylene bis-silanols in particular, along with a procedure for polymerizing these and other arylene-type bis-silanols using phosgene as a polymerization promotor or catalyst, to obtain highly purified, high molecular weight arylene-siloxanylene polymers having the characteristic structure: STR1 where Y is an arylene or substituted arylene moiety; R and R' are the same or different alkyl group(s), substituted alkyl group(s) or a phenyl group, x ranges from about 1 to 3 and n ranges from about 300 to 1500; said polymers having molecular weights (number average) of 100,000 and higher. Preferred polymers are those arylenesiloxanylenecarbonate polymers which, when laminated to polycarbonate sheets or glass maintain their transparency, stability and adherence to said substrates at temperatures of up to and including 400° F. Such polymers are useful for the formulation of high temperature interlayers for windshields and canopies for aircraft and related aerospace vehicles.
