Check Digit Verification of cas no

The CAS Registry Mumber 139517-26-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,1 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139517-26:
(8*1)+(7*3)+(6*9)+(5*5)+(4*1)+(3*7)+(2*2)+(1*6)=143
143 % 10 = 3
So 139517-26-3 is a valid CAS Registry Number.

New Aspects in the Regioselective Functionalization of Furans. Synthesis of Tri- and Tetrasubstituted Furan Derivatives.

Dominguez, Carmen,Csaky, Aurelio G.,Plumet, Joaquin

, p. 149 - 158 (1992)

Application of directed ortho metalation reaction and electrophilic aromatic substitution allows for the regioselective synthesis of tri- and tetrasubstituted furans, thus superseding classical de novo furan construction modes. Key Words: Furan functionalization; imidazolidine; oxazoline; electrophilic aromatic substitution; 1J(13C-H)
