Check Digit Verification of cas no
The CAS Registry Mumber 199191-93-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,9 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 199191-93:
(8*1)+(7*9)+(6*9)+(5*1)+(4*9)+(3*1)+(2*9)+(1*3)=190
190 % 10 = 0
So 199191-93-0 is a valid CAS Registry Number.

Bu3SnH mediated oxidative radical cyclisation onto imidazoles and pyrroles
Aldabbagh, Fawaz,Russell Bowman,Mann, Emma,Slawin, Alexandra M.Z.
, p. 8111 - 8128 (2007/10/03)
A new protocol using radical cyclisation has been developed for the synthesis of [1,2-c]-fused imidazoles and [1,2-a]-fused pyrroles. The intermediate nucleophilic N-alkyl radicals, generated using Bu3SnH from N- (ω-bromoalkyl) or N-[ω-(phenylselanyl)alkyl] imidazoles and pyrroles, undergo regio-selective radical cyclisalion onto the azole rings followed by oxidative re-aromatisation.
