Check Digit Verification of cas no

The CAS Registry Mumber 680204-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,2,0 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 680204-11:
(8*6)+(7*8)+(6*0)+(5*2)+(4*0)+(3*4)+(2*1)+(1*1)=129
129 % 10 = 9
So 680204-11-9 is a valid CAS Registry Number.

Synthetic studies on ciguatoxin: A highly convergent synthesis of the GHIJKLM ring system based on b-alkyl suzuki coupling

Takakura, Hiroyuki,Noguchi, Katsuhiko,Sasaki, Makoto,Tachibana, Kazuo

, p. 1090 - 1093 (2007/10/03)

Access to polycyclic polyethers is facilitated by a synthetic strategy involving two-step B-alkyl Suzuki coupling reactions for the stereo-selective construction of the polyether skeleton. Thus, a convergent synthetic route to the heptacyclic GHIJKLM ring system 1 of ciguatoxin, a marine algal toxin implicated in ciguatera fish poisoning, was developed. Bn = benzyl.
