Check Digit Verification of cas no

The CAS Registry Mumber 1589488-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,9,4,8 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1589488-83:
(9*1)+(8*5)+(7*8)+(6*9)+(5*4)+(4*8)+(3*8)+(2*8)+(1*3)=254
254 % 10 = 4
So 1589488-83-4 is a valid CAS Registry Number.

Three-component synthesis of dimethyl 7-aryl-8-(3-arylquinoxalin-2-yl)-2- (R-imino)-9-oxo-1,6-dioxa-spiro[4.4]nona-3,7-diene-3,4-dicarboxylates

Lisovenko,Dryahlov

, p. 1 - 6 (2014/05/06)

We have developed a method for the synthesis of dimethyl 7-aryl-8-(3-arylquinoxalin-2-yl)-2-(R-imino)-9-oxo-1,6-dioxaspiro[4.4]nona-3, 7-diene-3,4-dicarboxylates, based on a three-component reaction of 5-aryl-4-(quinoxalin-2-yl)furan-2,3-diones, 1-adamantylisocyanide or o-methylphenylisocyanide, and dimethyl acetylenedicarboxylate.
