Check Digit Verification of cas no

The CAS Registry Mumber 139399-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,9 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139399-68:
(8*1)+(7*3)+(6*9)+(5*3)+(4*9)+(3*9)+(2*6)+(1*8)=181
181 % 10 = 1
So 139399-68-1 is a valid CAS Registry Number.

Reexamination of the Thermolytic Rearrangement of 4-Halophenyl Azides to 2-Aminophenols and other Products

Gershon, H.,Clarke, D. D.,Gershon, M.

, p. 367 - 380 (1993)

The halogenation of derivatives of 2-aminophenol with N-chloro- and N-bromosuccinimides at ambient temperatures in acetic acid was studied.With the necessary compounds available, a reexamination of the thermolytic rearrangement of 2-halophenyl azides to 2-aminophenols and other products was undertaken.It is certain that the rearrangement of 4-halophenyl azides to 2-aminophenols occurs but the products identified in this study differ significantly from those reported previously by Suschitzky et al. (1963, 1966). Keywords: Acetylated-2-amino-5-halophenols; 2-Acetamido-5-haloanisoles; 6-Halo-2-methylbenzoxazoles; 6-Halobenzoxazolones; 6-Halotriacetylaminophenols; 1H-NMR spectra; Fungicidal activity.
