3493-72-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3493-72-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,9 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3493-72:
(6*3)+(5*4)+(4*9)+(3*3)+(2*7)+(1*2)=99
99 % 10 = 9
So 3493-72-9 is a valid CAS Registry Number.

Intramolecular Reaction Between Nitro and Carbodi-imide Groups; A New Synthesis of 2-Arylbenzotriazoles

Houghton, Peter G.,Pipe, David F.,Rees, Charles W.

, p. 1471 - 1480 (2007/10/02)

1-(2-Nitrophenyl)-5-phenyltetrazole (5b) decomposes when heated to give nitrogen, carbon dioxide, and 2-phenylbenzotriazole (6) in high yield.This new molecular rearrangement proceeds via 2-nitrophenyl(phenyl)carbodi-imide (8).Other precursors of this carbodi-imide, i.e. oxadiazolone (10), oxadiazolethione (11), oxathiadiazole 2-oxide (12), and the aminimide (16), and carbodi-imide itself, all give 2-phenylbenzotriazole (6) on thermolysis, the last three in high yield.This reaction is general for diarylcarbodi-imides with an ortho nitro group, and their precursors, and it provides a useful new route to 2-arylbenzotriazoles.A sequence of electrocyclic ring closing and opening reactions (Scheme 5) is proposed as the mechanism of this process.The key intermediate, 2-phenyl-1,2,4-benzotriazin-3-one 1-oxide (19) has been isolated from a careful thermolysis of (12) in toluene; in solution it is in reversible equlibrium with the ring-opened form (20).This new nitro-carbodi-imide group interaction has been extended to the more stable nitrobiphenyl(phenyl)carbodi-imide (25) and nitronaphthyl(phenyl)carbodi-imide (24) which, on flash vacuum pyrolysis, give benzimidazophenanthridine (29) and benzindazole 1-oxide (32) respectively, in new rearrangements.
