129922-65-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 129922-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,2 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129922-65:
(8*1)+(7*2)+(6*9)+(5*9)+(4*2)+(3*2)+(2*6)+(1*5)=152
152 % 10 = 2
So 129922-65-2 is a valid CAS Registry Number.

Synthesis and Some Reactions of 2-(2-Aminoanilino)cycloheptapyrroles: Leading to 5H-Cycloheptapyrrolobenzodiazepine, a Novel 20? Antiaromatic System, and Cycloheptapyrrolobenzimidazoles

Abe, Noritaka,Ishikawa, Naomi,Hayashi, Takashi,Miura, Yoshiaki

, p. 1617 - 1622 (2007/10/02)

2-Chlorocycloheptapyrroles reacted with o-phenylenediamine to give 2-(2-aminoanilino)cycloheptapyrroles (2a,b) in good yields.Treatment of 2a and 2b with polyphosphoric acid afforded cycloheptapyrrolobenzimidazole (4a) in good yields.Treatment of 2b with acids gave 6-(ethoxycarbonyl) derivatives (4b) of 4a and 12H-5,13-dihydrocycloheptapyrrolobenzodiazepin-12-one (5).Compound 5 was methylated with methyl iodide in the presence of DBU to give 5H-12-methoxycycloheptapyrrolobenzodiazepine, a novel 20? antiaromatic system.Treatment of 2b with sodium ethoxide gave 4b and 2H-1-(cycloheptapyrrol-2-yl)-1,3-dihydrobenzimidazol-2-one (7a).Compound 5 rearranged to 7a in the refluxing sodium ethoxide-ethanol solution.Reactions of 2a and 2b with triethyl orthoformate gave corresponding 1-(cycloheptapyrrol-2-yl)benzimidazoles.Reactions of 2a and 2b with acetic anhydride are also mentioned.
