Check Digit Verification of cas no

The CAS Registry Mumber 104331-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,3,3 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104331-23:
(8*1)+(7*0)+(6*4)+(5*3)+(4*3)+(3*1)+(2*2)+(1*3)=69
69 % 10 = 9
So 104331-23-9 is a valid CAS Registry Number.

Use of the Electrophilic Arylation Reaction of Aryl-lead Triacetates in a Sythesis of (+/-)-Lycoramine

Ackland, Darren J.,Pinhey, John T.

, p. 2695 - 2700 (2007/10/02)

A formal total synthesis of (+/-)-lycoramine is reported.The quaternary carbon centre of the alkaloid was produced by a novel electrophilic arylation of the mixture of isomeric vinylogous keto esters (4) and (5) by 2,3-dimethoxyphenyl-lead triacetate.The resulting key intermediate (7c), which was formed in almost quantitative yield, was converted in a straightforward sequence into the formamide (25), from which the alkaloid has been produced previously by a Bischler-Napieralski cyclisation.Functional group protection was only required at one stage in the synthesis.
