Check Digit Verification of cas no

The CAS Registry Mumber 391609-36-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,6,0 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 391609-36:
(8*3)+(7*9)+(6*1)+(5*6)+(4*0)+(3*9)+(2*3)+(1*6)=162
162 % 10 = 2
So 391609-36-2 is a valid CAS Registry Number.

Iodine (III)-mediated generation of nitrogen-tethered orthoquinol acetates for the construction of oxygenated indole, quinoline, and phenanthridine alkaloid motifs

Pouysegu, Laurent,Avellan, Anne-Virginie,Quideau, Stephane

, p. 3425 - 3436 (2007/10/03)

Functionalized indole and quinoline derivatives are conveniently prepared from nitrogen-tethered 2-methoxyphenols via phenyliodine(III) diacetate mediated oxidative acetoxylation, followed by a fluoride- or base-induced intramolecular nucleophilic addition reaction. This regioselective Michael-type addition step is further discussed in view of the rearrangement of orthoquinol acetate intermediates into paraquinol acetates that is sometimes observed in situ. Application of this methodology to the synthesis of a functionalized phenanthridine, and its potential for the construction of polyoxygenated lycorine-type alkaloid skeleta are here described.
