909805-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909805-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,8,0 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 909805-45:
(8*9)+(7*0)+(6*9)+(5*8)+(4*0)+(3*5)+(2*4)+(1*5)=194
194 % 10 = 4
So 909805-45-4 is a valid CAS Registry Number.

Gold-catalyzed intramolecular allylation of silyl alkynes induced by silane alcoholysis
Park, Sangho,Lee, Daesung
, p. 10664 - 10665 (2007/10/03)
The activation of alkynyl allyl silanes with a cationic gold catalyst in the presence of alcohols provides vinyl silanes that contain the allyl group at the β-position and the alkoxysilyl group in cis-orientation. The bond reorganization process is most c
