6485-91-2 Usage
General Description
Diethoxychlorosilane, also known as DEC, is a chemical compound with the molecular formula C4H11ClO2Si. It is a colorless and flammable liquid that is soluble in organic solvents. DEC is commonly used as a crosslinking agent in the production of silicone polymers and resins, as well as a coupling agent in the synthesis of organosilicon compounds. It is also utilized as a precursor in the preparation of silica coatings and as a surface modifier for glass and metal substrates. DEC is known to be a hazardous chemical and should be handled with care, as it can cause skin and eye irritation, as well as respiratory issues if inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 6485-91-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6485-91:
(6*6)+(5*4)+(4*8)+(3*5)+(2*9)+(1*1)=122
122 % 10 = 2
So 6485-91-2 is a valid CAS Registry Number.

supporting information; experimental part, p. 5273 - 5277 (2010/10/21)
Beyond silanol: A branched siloxane oligomer bearing terminal dialkoxysilyl groups was nonhydrolytically synthesized by direct alkoxysilylation of a tetraalkoxysilane with a chlorodialkoxysilane in the presence of the Lewis acid BiCl3 (see scheme). The reaction proceeds without the formation of intermediate silanol groups, and provides a selective route for siloxane-based oligomers. (Chemical equation presented)
