Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 78560-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,6 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78560-45:
(7*7)+(6*8)+(5*5)+(4*6)+(3*0)+(2*4)+(1*5)=159
159 % 10 = 9
So 78560-45-9 is a valid CAS Registry Number.

Page/Page column 8-10, (2008/06/13)
The present invention relates to a process for preparing silicon compounds bearing fluoroalkyl groups by hydrosilylation of a fluoroolefin in the presence of a hydrosilylation catalyst, which comprises initially charging and heating a hydrogenchlorosilane, then metering in the fluoroolefin and reacting the reaction mixture and subsequently isolating the hydrosilylation product.
Process for preparing fluoroalkyl-containing organosilicon compounds, and their use
-
, (2008/06/13)
Fluoroalkyl organosilicon compounds are prepared by reacting fluoroolefins with organosilicon compounds that contain at least one H--Si group, in the presence of a Pt(0) complex catalyst. Further, fluoroalkylalkoxy organosilicon compounds are prepared by esterifying fluoroalkyl organosilicon compounds. The process proceeds uniformly under mild conditions with high yields and selectivities.
