1335517-32-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1335517-32-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,5,1 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1335517-32:
(9*1)+(8*3)+(7*3)+(6*5)+(5*5)+(4*1)+(3*7)+(2*3)+(1*2)=142
142 % 10 = 2
So 1335517-32-2 is a valid CAS Registry Number.

A simple synthesis of 5-(2-Aminophenyl)-1H-pyrazoles

Janjic, Monika,Prebil, Rok,Groselj, Uros,Kralj, David,Malavasic, Crt,Golobic, Amalija,Stare, Katarina,Dahmann, Georg,Stanovnik, Branko,Svete, Jurij

, p. 1703 - 1717 (2011)

A four-step synthesis of 1-substituted 5-(2-aminophenyl)-1H-pyrazoles 5 as a novel type of histamine analogs and versatile building blocks for further transformations was developed. The synthesis starts from commercially available 2-nitroacetophenone (12), which is converted into the enamino ketone 13 as the key intermediate. Cyclization of the key intermediate 13 with monosubstituted hydrazines 14a-14l afforded the 5-(2-nitrophenyl)-1H-pyrazoles 17a-17l. Finally, catalytic hydrogenation of the nitro compounds 17a, 17c-17e, and 17g-17j furnished the title compounds 5a, 5c-5e, and 5g-5j, respectively, in good yields. As demonstrated by some further transformations, additional functionalization of compounds 17 and 5 is feasible, either by electrophilic substitution at C(4) of the pyrazole ring, or at the NH2 group.
