Check Digit Verification of cas no

The CAS Registry Mumber 142505-40-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142505-40:
(8*1)+(7*4)+(6*2)+(5*5)+(4*0)+(3*5)+(2*4)+(1*0)=96
96 % 10 = 6
So 142505-40-6 is a valid CAS Registry Number.

The reaction of (2-alkylidenaminophenyl)sulfides with di-iso-propyl peroxydicarbonate: Radical versus non-radical pathway

Leardini,Nanni,Santori,Zanardi

, p. 3961 - 3970 (2007/10/02)

The reaction of 2-methylthio- or 2-phenylthioarylimines with di-iso-propyl peroxydicarbonate (DPDC) is described. The phenylthio-derivatives undergo cyclization to benzothiazoles via a free-radical mechanism, whereas the methylthio-analogs afford arylthiomethyl iso-propyl carbonates, together with benzothiazoles as well; this last result could be accounted for with the intervention of a non-radical mechanism operating side by side with the radical one.
