Check Digit Verification of cas no

The CAS Registry Mumber 321534-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,5,3 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 321534-83:
(8*3)+(7*2)+(6*1)+(5*5)+(4*3)+(3*4)+(2*8)+(1*3)=112
112 % 10 = 2
So 321534-83-2 is a valid CAS Registry Number.

Concise route to 3-arylisoquinoline skeleton by lewis acid catalyzed c(sp3)-h bond functionalization and its application to formal synthesis of (±)-Tetrahydropalmatine

Mori, Keiji,Kawasaki, Taro,Akiyama, Takahiko

, p. 1436 - 1439 (2012/05/05)

An expeditious route to furnish an isoquinoline skeleton via hydride shift mediated C-H bond functionalization was developed. In this process, an unusual [1,5]-H shift without the assistance of the adjacent heteroatom took place to produce tetrahydroisoquinoline derivatives in good to excellent chemical yields. The formal synthesis of (±)-tetrahydropalmatine was achieved by exploiting this new transformation.

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.
