1196996-66-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1196996-66-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,6,9,9 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1196996-66:
(9*1)+(8*1)+(7*9)+(6*6)+(5*9)+(4*9)+(3*6)+(2*6)+(1*6)=233
233 % 10 = 3
So 1196996-66-3 is a valid CAS Registry Number.

Asymmetric total synthesis of tetrahydroprotoberberine derivatives and evaluation of their binding affinities at dopamine receptors

Lee, David Y.W.,Liu, Jing,Zhang, Shuzhen,Huang, Peng,Liu-Chen, Lee-Yuan

, p. 1437 - 1440 (2017/03/08)

Cocaine addiction remains a serious challenge for clinical and medical research because there is no effective pharmacological treatment. L-THP, a natural product isolated from Corydalis yanhusuo W.T. Wang, is one of the most frequently used traditional herbs to treat drug addiction in China. Our laboratory first reported that its demethylated metabolites L-ICP, L-CD, and L-CP had high affinity at dopamine D1, D2, and D5 receptors. Here we report the chemical synthesis of these metabolites and other derivatives and their binding affinities at dopamine receptors. The synthesis of these bioactive metabolites will allow further in vivo study of their potential in treating cocaine addiction.
