Check Digit Verification of cas no

The CAS Registry Mumber 503070-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,7 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 503070-99:
(8*5)+(7*0)+(6*3)+(5*0)+(4*7)+(3*0)+(2*9)+(1*9)=113
113 % 10 = 3
So 503070-99-3 is a valid CAS Registry Number.

Enantioselective synthesis of protected D-serine from tetrahydrooxazin-4-one via a hetero Diels-Alder reaction

Panunzio, Mauro,Bandini, Elisa,Campana, Eileen,Vicennati, Paola

, p. 2113 - 2115 (2002)

Hetero Diels-Alder reaction between 2-aza-3-trimethylsilyloxy-1,3-diene and aldehydes gives rise to tetrahydrooxazin-4-ones, useful intermediates in the synthesis of α-amino-β-hydroxy acids. Herein we report the complete stereoselective synthesis of D-serine Cbz-methyl ester.
