97181-50-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97181-50-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,8 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97181-50:
(7*9)+(6*7)+(5*1)+(4*8)+(3*1)+(2*5)+(1*0)=155
155 % 10 = 5
So 97181-50-5 is a valid CAS Registry Number.

Synthesis and structure-activity relationships of naphthamides as dopamine D3 receptor ligands

Huang,Luedtke,Freeman,Wu,Mach

, p. 1815 - 1826 (2007/10/03)

A series of naphthamides were synthesized, and the affinities of these compounds were determined for dopamine D2 and D3 receptors using radioligand binding techniques. The naphthamide compounds that were prepared include N-(1- alkylp

Synthesis and gastrointestinal prokinetic activity of novel benzamide derivatives with amphoteric side chains

Sakaguchi,Iwasaki,Iwanaga,Saito,Takahara,Kato,Hanaoka

, p. 424 - 436 (2007/10/03)

Novel benzamide derivatives (19-24, 32a-c, 43d-f), each possessing a cycloaminoalkanecarboxylic acid side chain, were synthesized and their gastrointestinal prokinetic and dopamine D2 receptor antagonist activities were evaluated. 4-[(4-Amino-5

18F-labeled benzamides for studying the dopamine D2 receptor with positron emission tomography

Mach,Leudtke,Unsworth,Boundy,Nowak,Scripko,Elder,Jackson,Hoffman,Evora,Rao,Molinoff,Childers,Ehrenkaufer

, p. 3707 - 3720 (2007/10/02)

Two series of (N-benzylpiperidin-4-yl)- and (9-azabicyclo[3.3.1]nonan- 3β-yl)benzamides were prepared, and in vitro binding assays were used to measure the affinity of these compounds for dopamine D2, dopamine D3, serotonin 5-HT2, and α2-adrenergic receptors. The results of these studies indicated compounds 23, 26b, and 34 have the selectivity needed for in vivo studies of the D2 (and possibly D3) receptors. 18F-Labeled analogues of 23, 26b and 34 were prepared by N-alkylation of the corresponding desbenzyl precursors with [18F]-4-fluorobenzyl iodide. Preliminary in vivo studies demonstrated that [18F]-23 and [18F]-26b are suitable candidates for further evaluation in positron emission tomography imaging studies. The slow rate of washout of [18F]-34 from nondopaminergic regions and its comparatively high lipophilicity indicates that this compound may not be suitable for imaging studies because of a high level of nonspecific binding.
