Check Digit Verification of cas no

The CAS Registry Mumber 200723-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,7,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 200723-09:
(8*2)+(7*0)+(6*0)+(5*7)+(4*2)+(3*3)+(2*0)+(1*9)=77
77 % 10 = 7
So 200723-09-7 is a valid CAS Registry Number.

Partially Racemic Compounds as Brushtail Possum Urinary Metabolites

Carman, Raymond M.,Klika, Karel D.

, p. 651 - 657 (2007/10/02)

The hydroxycineole (2) and cineolic acid (3) obtained as urinary metabolites from the brushtail possum (Trichosurus vulpecula) after the ingestion of 1,8-cineole (1), are partial racemates.The compounds have been examined by gas chromatographic analysis over chiral stationary phases, and by the synthesis of optically pure enantiomers.Female possums show different enantiomeric ratios from males.Possible advantages to the animal in the use of a partial racemate as a pheromone are discussed.
