Check Digit Verification of cas no

The CAS Registry Mumber 41658-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,6,5 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 41658-03:
(7*4)+(6*1)+(5*6)+(4*5)+(3*8)+(2*0)+(1*3)=111
111 % 10 = 1
So 41658-03-1 is a valid CAS Registry Number.

Surfactant Micelles Enable Metal-Free Spirocyclization of Keto-Ynamides and Access to Aza-Spiro Scaffolds in Aqueous Media

Beltran, Frédéric,Vela-Gonzalez, Andrea V.,Knaub, Tatiana,Schmutz, Marc,Krafft, Marie Pierre,Miesch, Laurence

, p. 6989 - 6993 (2019)

Micellar solutions of cetyltrimethylammonium bromide (CTAB) surfactant allow the spirocyclization of keto-ynamides in an aqueous medium without recourse to transition-metal catalysis, enabling access in water to naturally occurring aza-spiro compounds with potential in drug discovery. The reaction was monitored by dynamic light scattering (DLS) and cryogenic transmission electron microscopy (cryo-TEM), which determined the morphology and change in size of the micelles before and after incorporation of the substrate and achievement of 5-endo-dig cyclization inside the micelles.

Discovery and Characterization of 1 H-1,2,3-Triazole Derivatives as Novel Prostanoid EP4 Receptor Antagonists for Cancer Immunotherapy

Yang, Jun-Jie,Yu, Wei-Wei,Hu, Long-Long,Liu, Wen-Juan,Lin, Xian-Hua,Wang, Wei,Zhang, Qiansen,Wang, Pei-Li,Tang, Shuo-Wen,Wang, Xin,Liu, Mingyao,Lu, Weiqiang,Zhang, Han-Kun

, p. 569 - 590 (2020/02/05)

The prostanoid EP4 receptor is one of the key receptors associated with inflammatory mediator PGE2-elicited immunosuppression in the tumor microenvironment. Blockade of EP4 signaling to enhance immunity-mediated tumor elimination has recently emerged as a promising strategy for cancer immunotherapy. In our efforts to discover novel subtype-selective EP4 antagonists, we designed and synthesized a class of 1H-1,2,3-triazole-based ligands that display low nanomolar antagonism activity toward the human EP4 receptor and excellent subtype selectivity. The most promising compound 59 exhibits single-digit nanomolar potency in the EP4 calcium flux and cAMP-response element reporter assays and effectively suppresses the expression of multiple immunosuppression-related genes in macrophage cells. On the basis of its favorable ADMET properties, compound 59 was chosen for further in vivo biological evaluation. Oral administration of compound 59 significantly inhibited tumor growth in the mouse CT26 colon carcinoma model accompanied by enhanced infiltration of cytotoxic T lymphocytes in the tumor tissue.
