Check Digit Verification of cas no

The CAS Registry Mumber 50667-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,6 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50667-88:
(7*5)+(6*0)+(5*6)+(4*6)+(3*7)+(2*8)+(1*8)=134
134 % 10 = 4
So 50667-88-4 is a valid CAS Registry Number.

Iron(II)/Persulfate Mediated Newman-Kwart Rearrangement

Gendron, Thibault,Pereira, Raul,Abdi, Hafsa Y.,Witney, Timothy H.,?rstad, Erik

, p. 274 - 278 (2020/01/02)

Herein, we report that iron(II)/ammonium persulfate in aqueous acetonitrile mediates the Newman-Kwart rearrangement of O-aryl carbamothioates. Electron-rich substrates react rapidly under moderate heating to afford the rearranged products in excellent yie

The Newman-Kwart rearrangement re-evaluated by microwave synthesis

Moseley, Jonathan D.,Sankey, Rosalind F.,Tang, Olivier N.,Gilday, John P.

, p. 4685 - 4689 (2007/10/03)

The Newman-Kwart rearrangement (NKR) has been re-evaluated by microwave heating. Microwave technology has proven to be ideal for investigating this high temperature rearrangement and facilitated the confirmation of many aspects of this valuable reaction.
