Check Digit Verification of cas no
The CAS Registry Mumber 2897-60-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2897-60:
(6*2)+(5*8)+(4*9)+(3*7)+(2*6)+(1*0)=121
121 % 10 = 1
So 2897-60-1 is a valid CAS Registry Number.

Preparation method of epoxy silane coupling agent
-
Paragraph 0045; 0050, (2021/05/05)
The invention provides a preparation method of an epoxy silane coupling agent. The preparation method comprises the following steps: (1) synthesizing diallyl ether from chloropropene and allyl alcohol under the action of a catalyst and an alkali; (2) carrying out a hydrosilylation reaction on the diallyl ether and hydrogen-containing chlorosilane under the action of a platinum catalyst to obtain allyloxopropyl chlorosilane; (3) carrying out esterification reaction on the allyloxopropyl chlorosilane and saturated alcohol to obtain allyloxoalkoxy silane; and (4) carrying out epoxidation on the allyloxyalkoxy silane by using an oxidizing agent, so as to obtain gamma-(2, 3-epoxypropoxypropyl)alkoxy silane. The preparation method provided by the invention can be suitable for all gamma-(2, 3-epoxypropoxypropyl) epoxy silane, the used catalyst and raw materials are easy to obtain, the yield is high, and the industrial feasibility is high.
Unexpected silicon group transfer in difunctional alkoxy silanes
Filipkowski, Michelle A.,Petty, Herbert E.,Westmeyer, Mark D.,Schilling Jr., Curtis L.
, p. 15 - 19 (2013/09/06)
During the hydrosilylation reaction of a difunctional silane with allyl glycidyl ether (AGE), two scrambled hydrosilylation products were produced in significant amounts. This scrambling is reaction condition dependent and has been observed in a few other examples. It appears to be the first such alkoxysilane transformation to occur under these conditions, although similar siloxane transformations have been documented. This also introduces a method of preparing certain organofunctional alkyldialkoxysilanes in high purities via hydrosilylation, where the close boiling rearrangement by-products are minimized.
