Check Digit Verification of cas no

The CAS Registry Mumber 97022-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,0,2 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97022-17:
(7*9)+(6*7)+(5*0)+(4*2)+(3*2)+(2*1)+(1*7)=128
128 % 10 = 8
So 97022-17-8 is a valid CAS Registry Number.

Synthesis of two nuphar alkaloids by allenic hydroxylamine cyclisation

Bates, Roderick W.,Lim, Chia Juan

scheme or table, p. 866 - 868 (2010/06/11)

A highly diastereoselective silver-catalysed cyclisation of a 2-substituted β-allenic hydroxylamine is reported. The resulting trans-isoxazolidine is converted into two Nuphar alkaloids by a sequence involving cross-metathesis and intramolecular reductive amination. Georg Thieme Verlag Stuttgart - New York.
