89185-35-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89185-35-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,8 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89185-35:
(7*8)+(6*9)+(5*1)+(4*8)+(3*5)+(2*3)+(1*5)=173
173 % 10 = 3
So 89185-35-3 is a valid CAS Registry Number.

A regioselective synthesis of nitrosoimidazoheterocycles from the reaction of 2-aminopyridines and acetophenones in the presence of NaNO2and I2is described. The reaction is suggested to proceed by a domino process involving sequentia

Convenient Synthesis of Fused Heterocycles from α-Ketohydroximoyl Chlorides and Heterocyclic Amines

Parkanyi, Cyril,Abdelhamid, Abdou O.,Cheng, John C. S.

, p. 1029 - 1032 (2007/10/02)

Nitroso derivatives of imidazopyridine (11,13,14), imidazopyrimidine (15), imidazopyrazine (16), imidazopyrazole (17), and imidazo-1,2,4-triazole (19) were obtained in good yields from α-ketohydroximoyl chlorides 3 and 2-aminopyrazines (4-6), 2-aminopyrimidine (7), 2-aminopyrazine (8), 5-amino-3-phenylpyrazole (9), and 3-amino-2H-1,2,4-triazole (10), respectively.Under different conditions, the reaction of 3 with 3-amino-2H-1,2,4-triazole (10) and 2-aminopyrazine (8) afforded the noncyclized substitution products 18 and 22, respectively.The structures of the products were assigned and confirmed on the basis of their elemental analyses, spectral data, and alternate synthesis wherever possible.
