Check Digit Verification of cas no

The CAS Registry Mumber 199540-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,5,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199540-02:
(8*1)+(7*9)+(6*9)+(5*5)+(4*4)+(3*0)+(2*0)+(1*2)=168
168 % 10 = 8
So 199540-02-8 is a valid CAS Registry Number.

One-pot tandem enantioselective hydrogenation-hydroformylation synthesis of cyclic α-amino acids

Teoh, Euneace,Campi, Eva M.,Jackson, W. Roy,Robinson, Andrea J.

, p. 387 - 394 (2007/10/03)

Five- and six-membered cyclic amino acids can be prepared in good yield with high ee (> 95%) via tandem rhodium-DuPHOS catalysed asymmetric hydrogenation followed by a rhodium-catalysed hydroformylation-cyclisation sequence in a single pot. The synthesis can be achieved using Rh-DuPHOS as the sole catalyst.
