Check Digit Verification of cas no

The CAS Registry Mumber 18998-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,9 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18998-49:
(7*1)+(6*8)+(5*9)+(4*9)+(3*8)+(2*4)+(1*9)=177
177 % 10 = 7
So 18998-49-7 is a valid CAS Registry Number.

Thirty-three 4-amino-1,2,4-triazole derivatives 1–33 were synthesized by reacting 4-amino-1,2,4-triazole with a variety of benzaldehydes. The synthetic molecules were characterized via 1H NMR and EI-MS spectroscopic techniques and evaluated for

An Efficient Synthesis and Antibacterial Activity of Some Novel 2-Azetidinone Derivatives of 4H-1,2,4-Triazoles Under Mild Conditions

Khan, Takallum,Yadav, Ritu,Gound, Surendra Singh

supporting information, p. 1042 - 1047 (2018/02/23)

We have synthesized the novel 2-azetidinone derivatives by using Schiff bases of 1,2,4-triazoles via a single step protocol. We used DABCO as a good homogenous, ecofriendly, highly reactive, easy to handle, and nontoxic catalyst. In?DABCO catalyzed synthesis of active 2-oxo-azetidine, a highly electrophilic ketene intermediate can react with weakly nucleophilic (N═CH) linkage, which is used as the precursor for the cycloaddition reaction to deliver the desired products in excellent yields with protic solvents. In addition, the DABCO as an economically viable and readily available catalyst is soluble in almost all solvents and their salts easily filtered off from the reaction medium. Moreover, this new synthetic protocol features high conversion in green solvents and a straightforward procedure.

Triazole and benzotriazole derivatives as novel inhibitors for p90 ribosomal S6 protein kinase 2: Synthesis, molecular docking and SAR analysis

Yuan, Jun,Zhong, Ye,Li, Shiliang,Zhao, Xue,Luan, Guoqin,Zhao, Zhenjiang,Huang, Jin,Li, Honglin,Xu, Yufang

A series of triazole and benzotriazole derivatives as novel p90 ribosomal S6 protein kinase 2 (RSK2) inhibitors were designed and synthesized. The in vitro activities against RSK2 were evaluated, and among 14 compounds, compounds 5, 6, 11, 12, 13 and 14 exhibited enzyme IC50 values of 8.91, 2.86, 3.19, 3.05, 4.49 and 2.09 μmol/L respectively. The proposed binding modes were simulated using molecular docking method, and the docking results coupled with the structure-activity relationship (SAR) analysis indicated that all these active compounds bound to the RSK2 ATP binding site at NTKD, and the electron-donating groups on the 4-position of phenyl were the determinant point for the inhibitory activity.
