Check Digit Verification of cas no

The CAS Registry Mumber 195196-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,1,9 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 195196-20:
(8*1)+(7*9)+(6*5)+(5*1)+(4*9)+(3*6)+(2*2)+(1*0)=164
164 % 10 = 4
So 195196-20-4 is a valid CAS Registry Number.

Totally stereocontrolled nitrone-ketene acetal based synthesis of (2S,3S)-N-benzoyl-and N-boc-phenylisoserine

Jost,Gimbert,Greene

, p. 6672 - 6677 (2007/10/03)

A novel, nitrone-ketene acetal based approach to enantiopure (2S,3S)-N- benzoyl- and N-boc-phenylisoserine has been realized. The convergent approach, which involves the intermediacy of isoxazolidinones, proceeds in up to 59% overall yield and requires only three operations from the starting nitrones.
