513-23-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 513-23-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 513-23:
(5*5)+(4*1)+(3*3)+(2*2)+(1*3)=45
45 % 10 = 5
So 513-23-5 is a valid CAS Registry Number.

(-) 3 Isothujone, a small nonnitrogenous molecule with antinociceptive activity in mice

Rice,Wilson

, p. 1054 - 1057 (2007/10/13)

(-) 3 isothujone and (+) 3 thujone were examined for antinociceptive activity using the hot plate and Nilsen tests. In the hot plate test (-) 3 isothujone (ED50 = 6.5 mg/kg) was found to be codeine like and equipotent with (-) Δ9 tetrahydrocannabinol while the racemic material was essentially half as potent as the levorotatory isomer. (+) 3 Thyjone was inactive in both antinociceptive tests as were several structural analogues of the 3 thujones. As with the THC's less antinociceptive activity was observed in the Nilsen test than in the hot plate assay. Acute toxicities for the 3 thujones were determined and vastly improved synthetic procedures have been developed for two long known but difficultly accessible 3 thujanols.
