The CAS Registry Mumber 28557-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28557-75:
(7*2)+(6*8)+(5*5)+(4*5)+(3*7)+(2*7)+(1*5)=147
147 % 10 = 7
So 28557-75-7 is a valid CAS Registry Number.

BICYCLIC 1,2-OXAZINE N-OXIDES. DIFFERENT BEHAVIOUR IN RING FISSION BETWEEN SYSTEMS DERIVED FROM 5- AND 6-MEMBERED RING CYCLIC ENAMINES

Daneo, S.,Pitacco, G.,Risaliti, A.,Valentin, E.

, p. 1499 - 1504 (2007/10/02)

1,2-Oxazine N-oxides derived from aminocyclohexenes open into the corresponding nitroalkylated trisubstituted enamines, whereas those derived from aminocyclopentenes give stable tetrasubstituted enamines.Both open-chain systems are easily hydrolyzed to the corresponding χ-nitrocycloalkanones.
