Check Digit Verification of cas no

The CAS Registry Mumber 1542549-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,5,4 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1542549-21:
(9*1)+(8*5)+(7*4)+(6*2)+(5*5)+(4*4)+(3*9)+(2*2)+(1*1)=162
162 % 10 = 2
So 1542549-21-2 is a valid CAS Registry Number.

Synthesis of biologically active seven-membered-ring heterocycles

Reekie, Tristan A.,Kavanagh, Madeline E.,Longworth, Mitchell,Kassiou, Michael

, p. 3211 - 3227 (2013/12/04)

Seven-membered rings that contain one or more heteroatoms are interesting motifs for organic synthesis. In addition to their synthetic interest, they play an important role in industrial and pharmaceutical chemistry with generally increased central nervous system activity when flanked by aromatic rings. Herein we report a brief summary of some key methods of preparation for seven-membered-ring heterocycles and how they have been applied to the synthesis of commercially desirable products. We then detail new methods that we have developed for the synthesis of biologically active compounds containing this motif. Georg Thieme Verlag Stuttgart New York.
