1193381-84-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1193381-84-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,3,8 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1193381-84:
(9*1)+(8*1)+(7*9)+(6*3)+(5*3)+(4*8)+(3*1)+(2*8)+(1*4)=168
168 % 10 = 8
So 1193381-84-8 is a valid CAS Registry Number.

A rapid and efficient synthesis of a new pyrrolobenzodiazocines via an intramolecular Friedel-Crafts reaction
BouzBouz, Samir,Sanselme, Morgane
, p. 5884 - 5887 (2009)
New pyrrolobenzodiazocines 3 have been prepared by an intramolecular Friedel-Crafts process from pyrrolobenzoacrylamides 2. The cyclisation process involving a 1,4-intramolecular addition of a pyrrole onto acrylamide led to the formation of an eight-membe
