Check Digit Verification of cas no

The CAS Registry Mumber 1204401-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,4,0 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1204401-52:
(9*1)+(8*2)+(7*0)+(6*4)+(5*4)+(4*0)+(3*1)+(2*5)+(1*2)=84
84 % 10 = 4
So 1204401-52-4 is a valid CAS Registry Number.

Novel highly potent and selective σ1 receptor antagonists related to spipethiane

experimental part, p. 1261 - 1269 (2010/07/18)

Conservative chemical modifications of the core structure of the lead spipethiane (1) afforded novel potent σ1 ligands. σ1 affinity and σ1/σ2 selectivity proved to be favored by the introduction of polar functions (oxygen atom or carbonyl group) in position 3 or 4 (4-6) or by the elongation of the distance between the two hydrophobic portions of the molecule with the simultaneous presence of a carbonyl group in position 4 (8 and 9). The observed cytostatic effect against the human breast cancer cell line MCF-7/ADR, highly expressing σ1 receptors, and not against MCF-7, as well as the enhancement of morphine analgesia highlighted the σ1 antagonist profile of this series of compounds. In particular, due to its high σ1 affinity (pKi = 10.28) and σ1/ σ2 selectivity ratio (29510), compound 9 might be a novel valuable tool for σ receptor characterization and a suitable template for the rational design of potential therapeutically useful σ1 antagonists. 2010 American Chemical Society.
