Check Digit Verification of cas no

The CAS Registry Mumber 287401-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,4,0 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 287401-44:
(8*2)+(7*8)+(6*7)+(5*4)+(4*0)+(3*1)+(2*4)+(1*4)=149
149 % 10 = 9
So 287401-44-9 is a valid CAS Registry Number.

The first syntheses of the 1-oxo-2-oxa-5-azaspiro[3.4]octane ring system found in oxazolomycin

Papillon, Julien P. N.,Taylor, Richard J. K.

, p. 1987 - 1990 (2007/10/03)

matrix presented L-Proline was utilized to prepare an optically active 1-oxo-2-oxa-5-azaspiro[3.4]octane for the first time. The synthesis of the racemic system, using a tandem aldol-lactonization reaction, is also described. Ruthenium tetroxide oxidation of these compounds afforded the corresponding spiro β-lactone γ-lactams.
