748798-77-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 748798-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,8,7,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 748798-77:
(8*7)+(7*4)+(6*8)+(5*7)+(4*9)+(3*8)+(2*7)+(1*7)=248
248 % 10 = 8
So 748798-77-8 is a valid CAS Registry Number.

Dopamine/serotonin receptor ligands. 9.1 oxygen-containing midsized heterocyclic ring systems and nonrigidized analogues. A step toward dopamine D5 receptor selectivity

Wittig, Thomas W.,Decker, Michael,Lehmann, Jochen

, p. 4155 - 4158 (2007/10/03)

Eleven-membered heterocycles (dibenz[g,j]-1-oxa-4-azacycloundecenes) and open-chain analogues were synthesized and investigated for affinities to human dopamine receptor subtypes. The moderately rigidized rings displayed nanomolar and subnanomolar Ki values at D1-like receptors with a significant D1 to D2 and a slight D5 to D 1 selectivity. The open-chain analogues showed lower affinities but significant D1 to D2 selectivities. Compound 3 (K i(D5) = 0.57 nmol) showed antagonistic or inverse agonistic binding characteristics in a functional Ca assay.
