Check Digit Verification of cas no

The CAS Registry Mumber 1449389-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,3,8 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1449389-89:
(9*1)+(8*4)+(7*4)+(6*9)+(5*3)+(4*8)+(3*9)+(2*8)+(1*9)=222
222 % 10 = 2
So 1449389-89-2 is a valid CAS Registry Number.

Electrochemical HI-mediated Intermolecular C-N Bond Formation to Synthesize Imidazoles from Aryl Ketones and Benzylamines

Yang, Zan,Zhang, Jiaqi,Hu, Liping,Li, An,Li, Lijun,Liu, Kun,Yang, Tao,Zhou, Congshan

, p. 5952 - 5958 (2020/05/22)

An efficient and novel electrochemical oxidative tandem cyclization of aryl ketones and benzylamines for the synthesis of 1,2,4-trisubstituted-(1H)-imidazoles has been developed under metal- and oxidant-free conditions. This direct C-N bond formation strategy, with a broad functional group tolerance, affords the desired imidazoles in moderate to excellent yields.

, p. 26 - 31 (2019/03/26)

A novel synthetic strategy for the construction of substituted imidazoles from acetophenones and benzylamines via N-heterocyclic carbene (NHC) - catalysis was reported. This reaction can be performed under solvent-free condition without pre-functionalization of substrates. Various substituted acetophenones and benzylamines were converted to its corresponding imidazoles with good to excellent yields.

Practical synthesis of polysubstituted imidazoles via iodine- Catalyzed aerobic oxidative cyclization of aryl ketones and benzylamines

Huang, Huawen,Ji, Xiaochen,Wu, Wanqing,Jiang, Huanfeng

, p. 170 - 180 (2013/03/13)

A practical synthetic method for polysubstituted imidazoles via iodine-catalyzed aerobic oxidative cyclization of aryl ketones and benzylamines has been developed. It was found to tolerate a broad range of substrates to prepare polysubstituted imidazole derivatives in a one-pot manner, and thus importantly allowed product diversity for imidazole chemistry. Additionally, the resultant 1,2,4-trisubstituted imidazoles could be conveniently transformed to functionalized 1,2,4,5-tetrasubstituted imidazoles via electrophilic substitution or direct C-H functionalization, or 2,4-diaryl-1H-imidazoles by debenzylation reaction, which further indicates potential applications of this method in synthetic and pharmaceutical chemistry.
