Check Digit Verification of cas no
The CAS Registry Mumber 169693-29-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,6,9 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 169693-29:
(8*1)+(7*6)+(6*9)+(5*6)+(4*9)+(3*3)+(2*2)+(1*9)=192
192 % 10 = 2
So 169693-29-2 is a valid CAS Registry Number.

Development of a Friedel-Crafts triflation
Grundl, Marc A.,Kaster, Anne,Beaulieu, Ellen D.,Trauner, Dirk
, p. 5429 - 5432 (2007/10/03)
The development of a new variant of the Friedel-Crafts reaction that yields 3-aryl enol triflates is described. The reaction is practical, is atom-economical, and works well with electron-rich arene substrates.
