Check Digit Verification of cas no

The CAS Registry Mumber 1190370-56-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,3,7 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1190370-56:
(9*1)+(8*1)+(7*9)+(6*0)+(5*3)+(4*7)+(3*0)+(2*5)+(1*6)=139
139 % 10 = 9
So 1190370-56-9 is a valid CAS Registry Number.

Facile synthesis of fluorinated benzofuro- and benzothieno[2,3-b]pyridines, α-carbolines and nucleosides containing the α-carboline framework

Iaroshenko, Viktor O.,Wang, Yan,Zhang, Biao,Volochnyuk, Dmitriy,Sosnovskikh, Vyacheslav Ya.

experimental part, p. 2393 - 2402 (2010/01/16)

Fluorinated benzofuro[2,3-b]pyridines, benzothieno[ 2,3-b]pyridines and 9H-pyrido[2,3-b]indoles (α-carbolines) were synthesized via regiospecific pyridine core annulation of a number of fluoro-containing 1,3-CCC- dielectrophiles to benzofuran-2-amine, benzothiophen-2-amine and 1H-indol-2-amine. Based on the 2,4-bis(trifluoromethyl)-9H-pyrido[2,3-b]indole thus synthesized, the preparative approach towards a set of nucleosides and nucleoside mimetics bearing the α-carboline framework was elaborated.
