55214-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55214-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,1 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55214-31:
(7*5)+(6*5)+(5*2)+(4*1)+(3*4)+(2*3)+(1*1)=98
98 % 10 = 8
So 55214-31-8 is a valid CAS Registry Number.

Design, synthesis, and biological evaluation of structurally constrained hybrid analogues containing ropinirole moiety as a novel class of potent and selective dopamine D3 receptor ligands

Zhou, Benhua,Hong, Kwon Ho,Ji, Min,Cai, Jin

, p. 1597 - 1609 (2018/07/31)

Two series of hybrid analogues were designed, synthesized, and evaluated as a novel class of selective ligands for the dopamine D3 receptor. Binding affinities of target compounds were determined (using the method of radioligand binding assay). Compared to comparator agent BP897, compounds 2a and 2c were found to demonstrate a considerable binding affinity and selectivity for D3 receptor, and especially compound 2h was similarly potent and more selective D3R ligand than BP897, a positive reference. Thus, they may provide valuable information for the discovery and development of highly potent dopamine D3 receptor ligands with outstanding selectivity.

Benzo- and thieno-triazine-1,2,3 ones-4

-

, (2008/06/13)

This invention relates to benzo- and thieno-triazine-1,2,3 ones-4 represented by the formula STR1 in which m is 2, 3 or 4, X is the vinylene group --CH=CH-- or a sulfur atom; R1 and R2 can be alike or different and are hydrogen, halogen, a lower alkyl radical, lower alkoxy radical or trifluoromethyl radical; when X is --CH--CH-- n is 0, 1 or 2 and R is hydrogen, halogen, a lower alkyl radical, lower alkoxy radical or nitro group; when X is a sulfur atom, R is hydrogen or constitutes a --CH2 --4 chain between the two open positions of the thiophenic ring. The compounds are useful as antidepressant drugs.
