Check Digit Verification of cas no

The CAS Registry Mumber 1414781-37-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,4,7,8 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1414781-37:
(9*1)+(8*4)+(7*1)+(6*4)+(5*7)+(4*8)+(3*1)+(2*3)+(1*7)=155
155 % 10 = 5
So 1414781-37-5 is a valid CAS Registry Number.

Synthesis, structure-activity relationship and binding mode analysis of 4-thiazolidinone derivatives as novel inhibitors of human dihydroorotate dehydrogenase

Zeng, Fanxun,Qi, Tiantian,Li, Chunyan,Li, Tingfang,Li, Honglin,Li, Shiliang,Zhu, Lili,Xu, Xiaoyong

, p. 1297 - 1302 (2017)

A series of 4-thiazolidinone derivatives were synthesized and evaluated as novel human dihydroorotate dehydrogenase (hDHODH) inhibitors. Compounds 26 and 31 displayed IC50 values of 1.75 and 1.12 μM, respectively. The structure-activity relationship was summarized. Further binding mode analysis revealed that compound 31 could form a hydrogen bond with Tyr38 and a water-mediated hydrogen bond with Ala55, which may be necessary for maintaining the bioactivities of the compounds in this series. Further structural optimization of the para- or meta-position of the phenyl group at R will lead to the identification of more potent hDHODH inhibitors.

Facile and versatile synthesis of alkyl and aryl isothiocyanates by using triphosgene and cosolvent

Liu, Pengfei,Li, Chunyan,Zhang, Jingwei,Xu, Xiaoyong

supporting information, p. 3342 - 3351 (2013/10/01)

A mild and efficient method for the conversion of alkyl and aryl amines to isothiocyanates via dithiocarbamates has been developed using (CH 3)2CO-CS2 as co-solvent and triphosgene as dehydrosulfurization reagent. High yields, mild reaction conditions and excellent functional group compatibility make it become a versatile synthetic method for the preparation of isothiocyanates compared with reported methods.

Structural optimization and structure-activity relationships of N 2-(4-(4-methylpiperazin-1-yl)phenyl)- N 8-phenyl-9 H -purine-2,8-diamine derivatives, a new class of reversible kinase inhibitors targeting both EGFR-activating and resistance mutations

Yang, Jiao,Wang, Li-Jiao,Liu, Jing-Jing,Zhong, Lei,Zheng, Ren-Lin,Xu, Yong,Ji, Pan,Zhang, Chun-Hui,Wang, Wen-Jing,Lin, Xing-Dong,Li, Lin-Li,Wei, Yu-Quan,Yang, Sheng-Yong

, p. 10685 - 10699 (2013/02/22)

This paper describe the structural optimization of a hit compound, N 2-(4-(4-methylpiperazin-1-yl)phenyl)-N8-phenyl-9H-purine- 2,8-diamine (1), which is a reversible kinase inhibitor targeting both EGFR-activating and drug-resistance (T790M) mutations but has poor binding affinity. Structure-activity relationship studies led to the identification of 9-cyclopentyl-N2-(4-(4-methylpiperazin-1-yl)phenyl)-N 8-phenyl-9H-purine-2,8-diamine (9e) that exhibits significant in vitro antitumor potency against the non-small-cell lung cancer (NSCLC) cell lines HCC827 and H1975, which harbor EGFR-activating and drug-resistance mutations, respectively. Compound 9e was further assessed for potency and selectivity in enzymatic assays and in vivo anti-NSCLC studies. The results indicated that compound 9e is a highly potent kinase inhibitor against both EGFR-activating and resistance mutations and has good kinase spectrum selectivity across the kinome. In vivo, oral administration of compound 9e at a dose of 5 mg/kg caused rapid and complete tumor regression in a HCC827 xenograft model, and an oral dose of 50 mg/kg initiated a considerable antitumor effect in an H1975 xenograft model.
