Check Digit Verification of cas no
The CAS Registry Mumber 264146-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,1,4 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 264146-47:
(8*2)+(7*6)+(6*4)+(5*1)+(4*4)+(3*6)+(2*4)+(1*7)=136
136 % 10 = 6
So 264146-47-6 is a valid CAS Registry Number.

A high-yielding synthesis of the naturally occurring antitumour agent irisquinone
Hadfield, John A.,McGown, Alan T.,Butler, John
, p. 82 - 88 (2007/10/03)
A short, high-yielding synthesis of the antitumour agent irisquinone (1) is described. The key steps are the palladium catalysed coupling reaction of dec-9-yn-1-ol with iodide (2) to form alkyne (3) and the Fremy's salt oxidation of phenol (7).
