Check Digit Verification of cas no

The CAS Registry Mumber 98796-24-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,9 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98796-24:
(7*9)+(6*8)+(5*7)+(4*9)+(3*6)+(2*2)+(1*4)=208
208 % 10 = 8
So 98796-24-8 is a valid CAS Registry Number.

A route to regioselectively functionalized carbazoles, dibenzofurans, and dibenzothiophenes through anionic cyclization of benzyne-tethered aryllithiums

Sanz, Roberto,Fernandez, Yolanda,Castroviejo, Ma. Pilar,Perez, Antonio,Fananas, Francisco J.

, p. 6291 - 6294 (2007/10/03)

The treatment of 2-fluorophenyl 2-iodophenylamines, ether, and thioether, easily prepared from commercially available products, with 3.3 equiv of t-BuLi and further reaction with selected electrophiles gives rise to functionalized carbazole, dibenzofuran, and dibenzothiophene derivatives in a direct and regioselective manner. The process involves an anionic cyclization on a benzyne-tethered aryllithium intermediate.
