77523-20-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77523-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,2 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77523-20:
(7*7)+(6*7)+(5*5)+(4*2)+(3*3)+(2*2)+(1*0)=137
137 % 10 = 7
So 77523-20-7 is a valid CAS Registry Number.

Synthesis of Cannabinoid Model Compounds. Part 2): (3R,4R)-δ1(6)-Tetrahydrocannabinol-5"-oic Acid and 4"(R,S)-Methyl-(3R,4R)-δ1(6)-Tetrahydrocannabinol-5"-oic Acid

Franke, Ingo,Binder, Michael

, p. 2508 - 2514 (2007/10/02)

Two novel cannabinoid model compounds, (3R,4R)-Δ1(6)-tetrahydrocannabinol-5"-oic acid (22) and 4"(R,S)-methyl-(3R,4R)-Δ1(6)-tetrahydrocannabinol-5"-oic acid (23) were synthesized by acid-catalyzed condensation of (+)-trans-p-mentha-2,8-dien-1-ol (1) with the substituted resorcinols 18 and 19 obtained by a Wittig reaction between 3,5-bis(benzyloxy)benzaldehyde (7) and methyl 4-bromobutanoate (10) or methyl 4-bromo-2(R,S)-methylbutanoate (11) resp. with subsequent hydrogenation.The resulting methyl esters 20 and 21 were hydrolyzed to give acids 22 and 23.
