(8*1)+(7*0)+(6*9)+(5*0)+(4*0)+(3*0)+(2*2)+(1*2)=68
68 % 10 = 8
So 109000-22-8 is a valid CAS Registry Number.

A NEW ELECTROPHILIC ADDITION TO ACETYLENES. SYNTHESIS OF 1,2-IODOFUNCTIONALIZED OLEFINS
Barluenga, Jose,Rodriguez, Miguel A.,Gonzalez, Jose M.,Campos, Pedro J.
, p. 3303 - 3306 (1986)
Acetylenes react with bis(pyridine)iodo(I) tetrafluoroborate (1) in the presence of a wide variety of nucleophiles (F,Cl,Br,I,SCN,pyridine,OAc,anisole,H) to give 1,2-iodofunctionalized olelefins (4).
