Abstract
It is shown that the number of redshifted CO absorption-line systems which are found in the spectrum of the quasar PKS 0237-233, using the rules of Varshalovich and Levshakov (1981), differ insignificantly from that that would be expected from chance coincidences. Consequently, the CO systems proposed by Varshalovich and Levshakov have no physical reality.
