Check Digit Verification of cas no

The CAS Registry Mumber 67119-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,1 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67119-86:
(7*6)+(6*7)+(5*1)+(4*1)+(3*9)+(2*8)+(1*6)=142
142 % 10 = 2
So 67119-86-2 is a valid CAS Registry Number.

Synthesis of Racemic and Optically Active Δ9-Tetrahydrocannabinol (THC) Metabolites

Siegel, Craig,Gordon, Patrick M.,Uliss, David B.,Handrick, G. Richard,Dalzell, Haldean C.,Razdan, Raj. K.

, p. 6865 - 6872 (2007/10/02)

The preparation of racemic and optically active Δ9-THC metabolites is described from synthon 13.Racemic synthon 13 is prepared in four steps (46percent) from Danishefsky's diene.Optically active synthon 13 is prepared from perillaldehyde via the enone 22 in six steps (23percent yield).Alternatively, nopinone can be converted to 13 in three steps (50percent yield) via a cyclobutane ring cleavage.The acid-catalyzed condensation of 13 with olivetol (6a) and subsequent conversion to 11-hydroxy and 9-carboxyl Δ9-THC metabolites 2a and 4a is described, as well as the preparation of 1',1'-dimethylheptyl THC analogues 2b, 3b, and 4 b from 5-(1',1'-dimethylheptyl)resorcinol (6c).

An Optically Active Terpenic Synthon for Δ9-Cannabinoids: Synthesis of (-)-11-Hydroxy-Δ9-tetrahydrocannabinol (THC) and Its 1'.1'-Dimethylheptyl Analogue

Siegel, Craig,Gordon, Patrick M.,Razdan, Raj K.

, p. 5428 - 5430 (2007/10/02)

A facile entry into Δ9-tetrahydrocannabinoids has been achieved via synthon 1, synthesized from (R)-(+)-perillaldehyde in a six-step process (23percent overall yield).
