Check Digit Verification of cas no
The CAS Registry Mumber 109219-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,1 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109219-08:
(8*1)+(7*0)+(6*9)+(5*2)+(4*1)+(3*9)+(2*0)+(1*8)=111
111 % 10 = 1
So 109219-08-1 is a valid CAS Registry Number.

Zinc-mediated synthesis of diaryl selenides from diaryl diselenides and diaryliodonium salts in aqueous media
Movassagh, Barahman,Fazeli, Azadeh
, p. 194 - 196 (2006)
An efficient synthetic method has been developed for the preparation of symmetrical and unsymmetrical diaryl selenides through a one-pot reaction of diaryl diselenides and diaryliodonium salts in the presence of Zn/AlCl 3 system in aqueous media.
