174715-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174715-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,7,1 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174715-23:
(8*1)+(7*7)+(6*4)+(5*7)+(4*1)+(3*5)+(2*2)+(1*3)=142
142 % 10 = 2
So 174715-23-2 is a valid CAS Registry Number.

5-(α-fluorovinyl)-n-tosylindole
Gharat, Laxmikant A.,Martin, Arnold R.
, p. 185 - 189 (2007/10/02)
A α-fluorovinyl (or α-fluoroethene) substituent was introduced into the indole 5-position using an "atypical" Heck reaction. 5-Iodoindole (4) is preferred over 5-bromoindole as the starting material. Protection of the indole nitrogen is necessary.
