Check Digit Verification of cas no

The CAS Registry Mumber 1084909-78-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,4,9,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1084909-78:
(9*1)+(8*0)+(7*8)+(6*4)+(5*9)+(4*0)+(3*9)+(2*7)+(1*8)=183
183 % 10 = 3
So 1084909-78-3 is a valid CAS Registry Number.

Au-catalyzed synthesis of 5,6-dihydro-8H-indolizin-7-ones from N-(pent-2-en-4-ynyl)-β-lactams

Peng, Yu,Yu, Meng,Zhang, Liming

, p. 5187 - 5190 (2008)

(Chemical Equation Presented) Au-catalyzed synthesis of 5,6-dihydro-8H-indolizin-7-ones from readily available N-(pent-2-en-4-ynyl)- β-lactams is developed. In this reaction, a 5-exo-dig cyclization of the β-lactam nitrogen to the Au-activated C-C triple bond is followed by heterolytic fragmentation of the amide bond, forming a highly nucleophilic acyl cation. An expedient formal synthesis of indolizidine 167B was easily achieved using this new method.
