Check Digit Verification of cas no

The CAS Registry Mumber 548490-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,4,9 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 548490-86:
(8*5)+(7*4)+(6*8)+(5*4)+(4*9)+(3*0)+(2*8)+(1*6)=194
194 % 10 = 4
So 548490-86-4 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.
