Check Digit Verification of cas no

The CAS Registry Mumber 1175709-61-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,5,7,0 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1175709-61:
(9*1)+(8*1)+(7*7)+(6*5)+(5*7)+(4*0)+(3*9)+(2*6)+(1*1)=171
171 % 10 = 1
So 1175709-61-1 is a valid CAS Registry Number.

Synthesis of dihalo bi- and terpyridines by regioselective Suzuki-Miyaura cross-coupling reactions

Burzicki, Grégory,Voisin-Chiret, Anne Sophie,Oliveira Santos, Jana Sopkovà-de,Rault, Sylvain

experimental part, p. 5413 - 5417 (2009/10/24)

This paper describes an efficient and regioselective synthetic route leading to new dihalobi- and terpyridines. We developed a strategy based on regioselective sequence of Suzuki-Miyaura cross-coupling reactions between bromopyridyl boronic acids and dihalopyridines and dihalobipyridines. The study of the influence of the nature and the position of the halogen atoms leads to prepare bromoiododerivatives to obtain good selectivities.
