Check Digit Verification of cas no

The CAS Registry Mumber 1203590-61-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,3,5,9 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1203590-61:
(9*1)+(8*2)+(7*0)+(6*3)+(5*5)+(4*9)+(3*0)+(2*6)+(1*1)=117
117 % 10 = 7
So 1203590-61-7 is a valid CAS Registry Number.

ZnCl2-catalyzed intramolecular cyclization reaction of 2-aminochalcones using polymer-supported selenium reagent: Synthesis of 2-phenyl-4-quinolones and 2-phenyl-2,3-dihydroquinolin-4(1 H)-one

Tang,Chen, Bangzheng,Zhang, Lianpeng,Li, Wen,Lin, Jun

experimental part, p. 707 - 711 (2011/04/26)

A new and efficient method for the synthesis of 2-phenyl-4-quinolones and 2-phenyl-2,3-dihydroquinolin-4(1H)-ones is described. The reaction involves ZnCl2-mediated polystyrene-supported selenium-induced intramolecular cyclization of 2-amino-chalcones and subsequent traceless or functionalizing cleavage of selenium linker.
