Check Digit Verification of cas no

The CAS Registry Mumber 71265-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,6 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71265-20:
(7*7)+(6*1)+(5*2)+(4*6)+(3*5)+(2*2)+(1*0)=108
108 % 10 = 8
So 71265-20-8 is a valid CAS Registry Number.

Synthesis and Evaluation of PPARδAgonists That Promote Osteogenesis in a Human Mesenchymal Stem Cell Culture and in a Mouse Model of Human Osteoporosis

Kress, Brian J.,Kim, Dong Hyun,Mayo, Jared R.,Farris, Jeffery T.,Heck, Benjamin,Sarver, Jeffrey G.,Andy, Divya,Trendel, Jill A.,Heck, Bruce E.,Erhardt, Paul W.

, p. 6996 - 7032 (2021/05/29)

We synthesized a directed library of compounds to explore the structure-activity relationships of peroxisome proliferator-activated receptor δ(PPARδ) activation relative to mesenchymal stem cell (MSC) osteogenesis. Our scaffold used para-substituted cinnamic acids as a polar headgroup, a heteroatom and heterocycle core connecting units, and substituted phenyl groups for the lipophilic tail. Compounds were screened for their ability to increase osteogenesis in MSCs, and the most promising were examined for subunit specificity using a quantitative PPAR transactivation assay. Six compounds were selected for in vivo studies in an ovariectomized mouse model of human postmenopausal osteoporosis. Four compounds improved bone density in vivo, with two (12d and 31a) having activity comparable to that of GW0742, a well-studied PPARδ-selective agonist. 31a (2-methyl-4-[N-methyl-N-[5-methylene-4-methyl-2-[4-(trifluoromethyl)phenyl]thiazole]]aminocinnamic acid) had the highest selectivity for PPARδcompared to other subtypes, its selectivity far exceeding that of GW0742. Our results confirm that PPARδis a new drug target for possible treatment of osteoporosis via in situ manipulation of MSCs.

Expedient stereospecific Co-catalyzed tandem C-N and C-O bond formation of: N -methylanilines with styrene oxides

Satheesh, Vanaparthi,Vivek Kumar, Sundaravel,Punniyamurthy, Tharmalingam

, p. 11813 - 11816 (2018/12/01)

Cobalt(ii)-catalyzed stereospecific coupling of N-methylanilines with styrene oxides is developed via tandem C-N and C-O bond formation using tert-butyl hydroperoxide (TBHP) as an oxidant. Optically active epoxide can be reacted with high optical purity.
