Check Digit Verification of cas no

The CAS Registry Mumber 1178980-21-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,8,9,8 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1178980-21:
(9*1)+(8*1)+(7*7)+(6*8)+(5*9)+(4*8)+(3*0)+(2*2)+(1*1)=196
196 % 10 = 6
So 1178980-21-6 is a valid CAS Registry Number.

Diversity-oriented synthesis of substituted furo[2,3-b]pyrazines

Mehta, Vaibhav P.,Modha, Sachin G.,Ermolat'Ev, Denis,Van Hecke, Kristof,Van Meervelt, Luc,Van Der Eycken, Erik V.

experimental part, p. 27 - 41 (2009/07/25)

A highly efficient method for the synthesis of diversely substituted furo[2,3-b]pyrazines has been elaborated. The Ag+- or iodine-mediated electrophilic cyclization of readily generated 5-chloro-3-substituted ethynyl-1-(4-methoxybenzyl)-pyrazin-2(1H)-ones affords substituted furo[2,3-b]pyrazines, which undergo various palladium catalyzed reactions to generate a library of difficult to attain diversely substituted furo[2,3-b]pyrazines. CSIRO 2009.
