Check Digit Verification of cas no
The CAS Registry Mumber 143583-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143583-67:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*3)+(2*6)+(1*7)=139
139 % 10 = 9
So 143583-67-9 is a valid CAS Registry Number.

N-[2-(α-Bromoacetyl)phenyl]imides (prepared in two steps from 2-aminoacetophenone) gave, upon treatment with sodium azide, fused azidoquinolines via an intramolecular cyclization. Reaction of the above azides with phosphines gave N-heteryliminophosphoranes. The IR, 1H-, 13C-, and 31P-NMR and MS spectra of these compounds as well as the x-ray crystal structure of two of them is reported.
