Check Digit Verification of cas no

The CAS Registry Mumber 146142-35-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,1,4 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 146142-35:
(8*1)+(7*4)+(6*6)+(5*1)+(4*4)+(3*2)+(2*3)+(1*5)=110
110 % 10 = 0
So 146142-35-0 is a valid CAS Registry Number.

Synthesis and biological activity of enantiomeric oxapenemcarboxylic acids

Pfaendler,Neumann,Bartsch

, p. 1179 - 1184 (1992)

The synthesis of enantiomerically pure potassium (5R)- and (5S)-trans-2-tert-butyl-6-hydroxymethyloxapenem-3-carboxylates is reported. Surprisingly, both enantiomers were active antibiotics and β-lactamase inhibitors.
