1189122-34-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1189122-34-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,2 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1189122-34:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*2)+(3*2)+(2*3)+(1*4)=156
156 % 10 = 6
So 1189122-34-6 is a valid CAS Registry Number.

Hypervalent iodane mediated reactions of: N -acetyl enamines for the synthesis of oxazoles and imidazoles

Xu, Kang,Yang, Ruiqi,Yang, Shuang,Jiang, Cheng,Ding, Zhenhua

supporting information, p. 8977 - 8981 (2019/10/28)

A hypervalent iodane reagent used for the intramolecular cyclization of N-acetyl enamines and intermolecular cyclocondensation of enamines and nitriles was investigated. The reaction was performed under mild conditions and gave oxazoles and imidazoles, respectively, in moderate to excellent yields. This transformation exhibits good reactivity, selectivity and functional group tolerance. The selectivity of the intra- or intermolecular reaction is dependent on the structure of N-acetyl enamines.
