Check Digit Verification of cas no

The CAS Registry Mumber 65995-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,9 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 65995-42:
(7*6)+(6*5)+(5*9)+(4*9)+(3*5)+(2*4)+(1*2)=178
178 % 10 = 8
So 65995-42-8 is a valid CAS Registry Number.

Studies on inhibitory activity against acetylcholinesterase of new bisbenzylisoquinoline alkaloid and its related compounds

Ogino, Tatsunori,Yamaguchi, Takuji,Sato, Toshitsugu,Sasaki, Hiroshi,Sugama, Ko,Okada, Minoru,Maruno, Masao

, p. 2253 - 2260 (2007/10/03)

A new phenolic bisbenzylisoquinoline (BBI) alkaloid named 2′-N-norfangchinoline was isolated from the root of Stephania tetrandra S. MOORE along withfangchinoline (2) and atherospermoline (3). The chemical structure of 2′-N-norfangchinoline was proved to be 4 by spectral analyses and chemical methods. Moreover three phenolic BBI alkaloidal compounds, 2,2′-N,N-dinorfangchinoline (8), 2′-N-noratherospermoline (9), 2-N-norfangchinoline (10) were derived from tetrandrine (1). And 12-O-acetyl atherospermoline (11) was obtained by partial acetylation of atherospermoline (3). Seven phenolic BBI compounds (2, 3, 4, 8, 9, 10, and 11) also have the inhibitory effect on acetylcholinesterase.
