Check Digit Verification of cas no

The CAS Registry Mumber 25456-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,5 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25456-85:
(7*2)+(6*5)+(5*4)+(4*5)+(3*6)+(2*8)+(1*5)=123
123 % 10 = 3
So 25456-85-3 is a valid CAS Registry Number.

Asymmetric Synthesis of a New Proline Analogue

Vasella, Andrea,Voeffray, Robert

, p. 97 - 98 (2007/10/02)

The 1,3-dipolar cycloaddition to ethylene of N-glycosylnitrones, formed in situ from the partially protected D-mannose- or D-ribose-oximes and various glyoxalates, gave compounds which could be transformed into both enantiomers of 3-t-butoxycarbonyl-isoxazolidine and derivatives thereof.
