Check Digit Verification of cas no

The CAS Registry Mumber 351217-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,1,2,1 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 351217-83:
(8*3)+(7*5)+(6*1)+(5*2)+(4*1)+(3*7)+(2*8)+(1*3)=119
119 % 10 = 9
So 351217-83-9 is a valid CAS Registry Number.

From benzil arylimines to 2H-benzo-1,4-thiazines, benzothiazoles or indoles

Charrier, Jean-Damien,Landreau, Cyrille,Deniaud, David,Reliquet, Fran?oise,Reliquet, Alain,Meslin, Jean Claude

, p. 4195 - 4202 (2001)

A series of benzil monoarylimines (1) was treated with phosphorus pentasulfide in refluxing toluene or xylene. Thionation of 1 occurred readily to afford either 2H-benzo-1,4-thiazines (2) or indoles (4) via annulation reactions, depending strongly on the nature of the meta substituent of the arylamino group. Mechanisms for these rearrangements were proposed. Furthermore, subsequent oxidation of 2 provided benzothiazoles (3). All compounds were fully characterized by IR, MS, 13C and 1H NMR.
