Check Digit Verification of cas no

The CAS Registry Mumber 86046-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,0,4 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 86046-45:
(7*8)+(6*6)+(5*0)+(4*4)+(3*6)+(2*4)+(1*5)=139
139 % 10 = 9
So 86046-45-9 is a valid CAS Registry Number.

Phenolic Oxidative Coupling with Hypervalent Iodine. A Synthesis of 6a-Epipretazettine

White, James D.,Chong, Wesley K. M.,Thirring, Klaus

, p. 2300 - 2302 (2007/10/02)

6a-Epipretazettine was synthesized in seven steps from piperonal and synephrine.Intramolecular, monophenolic, oxidative coupling of a functionalized benzylic acetal, employing benzene as oxidant, gave a spirodienone in 13 percent yield.Subsequent deprotection of the secondary amine was followed by spontaneous closure to a tetracyclic pyrrolidine possessing an all-cis ring fusion.This substance was reduced with diisobutylaluminum hydride, and the resulting alcohol was transformed, via methanolysis of the corresponding mesylate, to O-methyl-6a-epipretazettine.Acidic hydrolysis of the latter yielded 6a-epipretazettine, identical with material previously obtained by Danishefsky.
