Check Digit Verification of cas no

The CAS Registry Mumber 220966-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,6 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 220966-22:
(8*2)+(7*2)+(6*0)+(5*9)+(4*6)+(3*6)+(2*2)+(1*2)=123
123 % 10 = 3
So 220966-22-3 is a valid CAS Registry Number.

Synthesis of isoindolo[1,3]benzoxazine derivatives through intramolecular arylation of N-acyliminium ions

Hucher, Nicolas,Daich, Adam,Decroix, Bernard

, p. 1477 - 1483 (1998)

[1,3]Benzoxazines annulated to isoindole as 3 and 4 have been synthesized in three steps from N-chloromethylphthalimide 5 and substituted phenols 6. The key step was the acid-catalyzed cyclization of ω-carbinol lactams 8 and 9.
