117609-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117609-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,0 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117609-05:
(8*1)+(7*1)+(6*7)+(5*6)+(4*0)+(3*9)+(2*0)+(1*5)=119
119 % 10 = 9
So 117609-05-9 is a valid CAS Registry Number.

A SIMPLE PROCEDURE FOR THE PREPARATION OF INDOLES
Lloyd, David H.,Nichols, David E.
, p. 4561 - 4562 (2007/10/02)
Indoles are easily prepared in 60-70percent yield from the corresponding o-nitrotoluenes by condensation with tripiperidinomethane, followed by reductive cyclization with aqueous titanous chloride.
