Check Digit Verification of cas no
The CAS Registry Mumber 91344-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91344-45:
(7*9)+(6*1)+(5*3)+(4*4)+(3*4)+(2*4)+(1*5)=125
125 % 10 = 5
So 91344-45-5 is a valid CAS Registry Number.

Heterocyclic Seven-Membered Ring Compounds, XXXV - The Thermal 1-Benzothiepine-Thionaphthole-Rearrangement
Hofmann, Hans,Goettfert, Christine,Gaube, Helmut
, p. 1059 - 1066 (2007/10/02)
On heating in carbon tetrachloride or nitromethane the 5-methoxy-1-benzothiepines 1-4 isomerize to the corresponding thionaphtholes 5-8, whereas in cyclohexane from 1-4 the usual desulfuration products C arise.Kinetic and thermodynamic data have been estimated for the reactions 3 -> 7 and 4 -> 8.If the thermal rearrangement of 3 resp. 4 takes place in presence of cyclohexene sulphide, one gets the desulfuration products C also in carbon tetrachloride or nitromethane as solvent together with the equimolar amount of cyclohexene.This behaviour leads to the assumption of a S2-spezies as the primary elimination product of sulphur from the episulphide intermediate A.
