171618-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171618-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,6,1 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 171618-52:
(8*1)+(7*7)+(6*1)+(5*6)+(4*1)+(3*8)+(2*5)+(1*2)=133
133 % 10 = 3
So 171618-52-3 is a valid CAS Registry Number.

Palladium acetate mediated synthesis of 3,4-benzo and naphtho-β-carbolines
Jeevanandam,Srinivasan
, p. 3427 - 3434 (2007/10/03)
An efficient synthesis of 2-(N-arylaminomethyl)indole derivatives 5 in good yields in four steps from 2-bromomethyl-3-phenylthio-1-benzenesulfonyl indole1 is reported. Palladium acetate mediated cyclisation of 5 gives benzo and naphtho-β-carbolines (6 and 7).
