The CAS Registry Mumber 84636-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,3 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84636-84:
(7*8)+(6*4)+(5*6)+(4*3)+(3*6)+(2*8)+(1*4)=160
160 % 10 = 0
So 84636-84-0 is a valid CAS Registry Number.

Synthesis of Spirooxazolidinones

Subbaraj, A.,Ramakrishnan, V. T.

, p. 506 - 513 (2007/10/02)

α-Chloro-N-arylacetamides (3) react with 2-methylcyclohexane-1,3-dione, 2-ethylcyclohexane-1,3-dione and 2,5,5-trimethylcyclohexane-1,3-dione to give the respective 4-aryl-spirooxazolidinones.An intermediate, 2-(2,5,5-trimethyl-3-oxocyclohexen-1-yloxy)-N-(p-tolyl)acetamide, has been isolated establishing the suggested mechanism of formation of the spirooxazolidinones.Also, general mass spectral fragmentation pattern is discussed.
