Check Digit Verification of cas no
The CAS Registry Mumber 28293-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28293-40:
(7*2)+(6*8)+(5*2)+(4*9)+(3*3)+(2*4)+(1*0)=125
125 % 10 = 5
So 28293-40-5 is a valid CAS Registry Number.

Sulfonium ylides derived from 2-hydroxy-benzoquinones: Crystal and molecular structure and their one-step conversion into Mannich bases by amine N-oxides
Rosenau, Thomas,Mereiter, Kurt,J?ger, Christian,Schmid, Peter,Kosma, Paul
, p. 5719 - 5723 (2004)
Reaction of 2-hydroxy-para-benzoquinones with DMSO/Ac2O produced dimethylsulfonium ylides, of which crystal structures as well as solid and liquid state NMR spectra were recorded. The ylides react with tertiary methylamine N-oxides in a one-pot, multi-step process to 3-methylamino- substituted benzoquinones. The mechanism starts with a deoxygenative deprotonation of the amine N-oxides, followed by a formal electrophilic displacement of DMSO by the resulting carbonium-iminium ion.
