117409-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117409-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,4,0 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117409-05:
(8*1)+(7*1)+(6*7)+(5*4)+(4*0)+(3*9)+(2*0)+(1*5)=109
109 % 10 = 9
So 117409-05-9 is a valid CAS Registry Number.

ENANTIOSELECTIVE HYDROSILYLATION OF ACETOPHENONE WITH RHODIUM /OXAZOLINES CATALYSTS
Balavoine, G.,Clinet, J.C.,Lellouche, I.
, p. 5141 - 5144 (1989)
N-chelate ligands based on chiral oxazolines are efficient co-catalysts in the enantioselective hydrosilylation of acetophenone with α-naphtylphenylsilane.Enantiomeric excess as up to 80percent have been achieved.
