Check Digit Verification of cas no
The CAS Registry Mumber 23003-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 23003-45:
(7*2)+(6*3)+(5*0)+(4*0)+(3*3)+(2*4)+(1*5)=54
54 % 10 = 4
So 23003-45-4 is a valid CAS Registry Number.

1,3-Dipolar Character of Six-membered Aromatic Rings. Part 55. 3-Hydroxypyridine-2-thiones: Betaines, Cycloadditions, and Other Reactions
Katritzky, Alan R.,Grzeskowiak, Nicholas E.

1-Methyl-2-methylthio-3-oxidopyridinium, 2-allylthio-1-methyl-3-oxidopyridinium, and 1--2-methylthio-3-oxidopyridinium undergo 1,3-dipolar cycloaddition to electron-deficient alkenes giving azabicyclooctene adducts having 1-alkylthio substituents.Quaternisation and tropone formation are investigated. 3-Hydroxypyridine-2-thione is cycloalkylated between sulphur and oxygen by substituted 1,1-dichloromethanes and certain α-haloacetyl chlorides. 1-(2-Pyridylmethyl)-3-oxidopyridinium gives azabicyclooctene cycloadducts with electron-deficient alkenes.The stereochemistry of all cycloadducts is deduced from the n.m.r.spectra.
