Check Digit Verification of cas no

The CAS Registry Mumber 1448021-10-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,0,2 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1448021-10:
(9*1)+(8*4)+(7*4)+(6*8)+(5*0)+(4*2)+(3*1)+(2*1)+(1*0)=130
130 % 10 = 0
So 1448021-10-0 is a valid CAS Registry Number.

Construction of functionalized tricyclic dihydropyrazino-quinazolinedione chemotypes via an Ugi/N-acyliminium ion cyclization cascade

Gunawan, Steven,Hulme, Christopher

, p. 4467 - 4470 (2013/07/26)

Dihydropyrazino-quinazolinedione chemotypes are complex and structurally challenging structures of biological interest, being found in the marine alkaloids such as brevianamide M-N and fumiquinazolines A-C. Herein we report the synthesis of this tricyclic system in three synthetic operations by means of an Ugi multi-component reaction (MCR) followed by a tandem N-acyliminium ion cyclization-intramolecular nucleophilic addition reaction sequence. Additional structural diversification for further library enrichment was also accomplished via sequential N-alkylation and N-acylation/sulfonation.
