Check Digit Verification of cas no
The CAS Registry Mumber 109746-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,4 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109746-09:
(8*1)+(7*0)+(6*9)+(5*7)+(4*4)+(3*6)+(2*0)+(1*9)=140
140 % 10 = 0
So 109746-09-0 is a valid CAS Registry Number.

Alkylation of Position C-5 of Triacetic Acid Lactone by Sigmatropic Rearrangement of Sulphonium Ylides
March, Pedro de,Moreno-Manas, Marcial,Ripoll, Isabel
, p. 1413 - 1420 (2007/10/02)
Reactions of the 4-methoxy-6-(phenylthiomethyl)-2H-pyran-2-ones 4 with three different diazo compounds under copper or rhodium catalysis give the corresponding sulphonium ylides, which through sigmatropic rearrangement and further prototropy afford the pyrones 6, functionalized at the difficultly accessible position C-5.Desulphurations of products 6 with deactivated Raney nickel give the pyrones 17-19.The influence of the experimental conditions on the competition between sigmatropic and Stevens rearrangement has been studied for the reaction of 4-methoxy-6-(phenylthiomethyl)-2H-pyran-2-one (4a) and dimethyl diazomalonate.Several products (9, 10, and 11) arising from sulphonium ylides equilibration and radical recombination have been found in addition to the sigmatropic and the Stevens rearrangement products 6d and 8.
