133609-26-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133609-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,0 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 133609-26:
(8*1)+(7*3)+(6*3)+(5*6)+(4*0)+(3*9)+(2*2)+(1*6)=114
114 % 10 = 4
So 133609-26-4 is a valid CAS Registry Number.

A Simple Synthesis of Amphimedine
Prager, Rolf H.,Tsopelas, Chris,Heisler, Teresa
, p. 277 - 285 (2007/10/02)
The marine alkaloid amphimedine has been synthesized by a short sequence of reactions commencing from the known indenopyridinedione (2).Reaction with 4-pyridillithium, followed by hydrazoic acid treatment, gave 5-(4-pyridyl)-3,6-phenanthrolin-4(3H)-one (1
