Check Digit Verification of cas no

The CAS Registry Mumber 224780-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,7,8 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 224780-82:
(8*2)+(7*2)+(6*4)+(5*7)+(4*8)+(3*0)+(2*8)+(1*2)=139
139 % 10 = 9
So 224780-82-9 is a valid CAS Registry Number.

Synthesis of 1β-methylcarbapenem antibiotic precursors by cyclization using π-allylpalladium complexes

Galland, Jean-Christophe,Roland, Sylvain,Malpart, Joel,Savignac, Monique,Genet, Jean-Pierre

, p. 621 - 626 (1999)

An efficient diastereoselective multi-step synthesis of bicyclic 1β- methylcarbapenem antibiotic precursors has been developed, starting from the commercially available 4-acetoxyazetidin-2-one 4. Chiral ruthenium catalysts are used in the hydrogenation st
