Check Digit Verification of cas no

The CAS Registry Mumber 185522-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,5,2 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 185522-68:
(8*1)+(7*8)+(6*5)+(5*5)+(4*2)+(3*2)+(2*6)+(1*8)=153
153 % 10 = 3
So 185522-68-3 is a valid CAS Registry Number.

Asymmetric 1,3-Dipolar Cycloaddition: Synthesis of N-protected (4S)-4-Hydroxy L-Glutamic Acid Diester

Gefflaut, Thierry,Bauer, Udo,Airola, Karri,Koskinen, Ari M. P.

, p. 3099 - 3102 (2007/10/03)

An asymmetric synthesis of N-protected (4S)-4-hydroxy L-glutamic acid diester is described.The key feature of the synthesis is the asymmetric 1,3-dipolar cycloaddition of nitrone 4 with 5, which provides stereoselectively the isoxazolidine with the correc
