Check Digit Verification of cas no

The CAS Registry Mumber 83345-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,4 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83345-83:
(7*8)+(6*3)+(5*3)+(4*4)+(3*5)+(2*8)+(1*3)=139
139 % 10 = 9
So 83345-83-9 is a valid CAS Registry Number.

N-Phehylsulphimide Formation and Rearrangement in the Thermal Reaction of Phenylnitrene with Sulphides

Benati, Luisa,Montevecchi, P. Carlo,Spagnolo, Piero

, p. 771 - 776 (2007/10/02)

Thermal reaction of phenyl azide (1) with thioanisole (2a), dimethyl sulphide (2b), and tetrahydrothiophen (2c) leads to the formation of 2-substituted anilines (3a-c) by Sommelet-Hauser rearrangement of the intermediate N-phenylsulphimides arising from phenylnitrene attack at the sulphur atom of (2a-c).Reaction with ethyl phenyl sulphide (2d) gives benzenesulphenanilide (8) and ethylene by cycloelimination of the resulting N-phenylsulphimide.Reaction with acyclic benzylic sulphides (2e-g) apparently leads only to the insertion products of phenylnitrene into benzylic C-H bond, presumably through Stevens rearrangement of the intermediate sulphimides, whereas Sommelet-Hauser rearrangement appears to compete favourably with Stevens rearrangement in the sulphimide resulting from reaction of phenylnitrene with the cyclic benzylic sulphide (2h).
