Check Digit Verification of cas no

The CAS Registry Mumber 521937-32-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,9,3 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 521937-32:
(8*5)+(7*2)+(6*1)+(5*9)+(4*3)+(3*7)+(2*3)+(1*2)=146
146 % 10 = 6
So 521937-32-6 is a valid CAS Registry Number.

, p. 289 - 290 (2007/10/03)

Enamino acids 2 and 5 undergo a facile cyclisation to afford the pyrrole 3 and isoindole 6 ring systems; a novel two atom ring expansion ensues when derivatives 5b,d are subjected to the cyclisation conditions, resulting in the formation of the new oxacin
