129572-33-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129572-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,7 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129572-33:
(8*1)+(7*2)+(6*9)+(5*5)+(4*7)+(3*2)+(2*3)+(1*3)=144
144 % 10 = 4
So 129572-33-4 is a valid CAS Registry Number.

Potent Anticonflict Activity and Lessening of Memory Impairment with a Series of Novel Benzothienopyridines and 1,2,3,4-Tetrahydrobenzothienopyridines

Kawakubo, Hiromu,Okazaki, Katuya,Nagatani, Tadasi,Takao, Katuyuki,Hasimoto, Shinichi,Sugihara, Taisuke

, p. 3110 - 3116 (2007/10/02)

Benzothienopyridines (10a-c, 11, 12a-t, and 13a,b) and 1,2,3,4-tetrahydrobenzothienopyridines (3a-c, 7, 8a-c, and 9) were synthesized.The compounds are bioisosteres of β-carbolines and 1,2,3,4-tetrahydro-β-carbolines where the indole nitrogen is replaced by sulfur.Their pharmacological activity was evaluated in a water lick conflict test in rats and a passive avoidance test in mice.In the 1,2,3,4-tetrahydrobenzothienopyridine series, the presence of ethyl ester (3b) or cyclohexyl carboxamide (7) groups at C-3 conferred good anticonflict activity and lessening of memory impairment, while N-acylation of 3b abolished activity.In the benzothienopyridine series, the aminoethyl carboxamide (12a) group at C-3 also conferred activity, but other amides studied were not active.The most potent compounds (3b, 7, and 12a) were also administered orally and had potent anticonflict and antiscopolamine amnesia-reversal activity.These compounds did not bind to the BZP receptor in spite of having structures similar to those of β-carbolines.Compound 7 bound strongly to 5-HT1A receptors and would be expected to be a novel anxiolytic.
