Check Digit Verification of cas no

The CAS Registry Mumber 173781-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,7,8 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 173781-70:
(8*1)+(7*7)+(6*3)+(5*7)+(4*8)+(3*1)+(2*7)+(1*0)=159
159 % 10 = 9
So 173781-70-9 is a valid CAS Registry Number.

4-Aminoquinolines: Novel nociceptin antagonists with analgesic activity

Shinkai,Ito,Iida,Kitao,Yamada,Uchida

, p. 4667 - 4677 (2007/10/03)

Small-molecule nociceptin antagonists were synthesized to examine their therapeutic potential. After a 4-aminoquinoline derivative was found to bind with the human ORL1 receptor, a series of 4-aminoquinolines and related compounds were synthesized and their binding was evaluated. Elucidation of structure - Activity relationships eventually led to the optimum compounds. One of these compounds, N-(4-amino-2-methylquinolin-6-yl)-2-(4-ethylphenoxymethyl)benzamide hydrochloride (11) not only antagonized nociceptin-induced allodynia in mice but also showed analgesic effect in a hot plate test using mice and in a formalin test using rats. Its analgesic effect was not antagonized by the opioid antagonist naloxone. These results indicate that this nociceptin antagonist has the potential to become a novel type of analgesic that differs from μ-opioid agonists.
