13122-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13122-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,2 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13122-67:
(7*1)+(6*3)+(5*1)+(4*2)+(3*2)+(2*6)+(1*7)=63
63 % 10 = 3
So 13122-67-3 is a valid CAS Registry Number.

Acyl acid derivative and preparation method and medical application thereof

-

Paragraph 0396-0399, (2020/07/02)

The invention relates to an acyl acid derivative as well as a preparation method and medical application thereof. Specifically, the invention relates to a compound represented by a general formula (I), a pharmaceutically acceptable salt thereof, or a pharmaceutical composition containing the same, and the invention also relates to a use thereof as an active ingredient in the prevention and/or treatment of muscle atrophy-related diseases, including myogenic muscle atrophy, disuse muscle atrophy, senile muscle atrophy, neurogenic muscle atrophy, and a use in the prevention and/or treatment of obesity, fatty liver, cardiovascular and cerebrovascular diseases, metabolic diseases, and anti-aging, wherein the definition of each group in the general formula (I) is the same as the definition in the specification.

Preparation and Application of Amino Phosphine Ligands Bearing Spiro[indane-1,2′-pyrrolidine] Backbone

Feng, Lifei,Jiao, Peng,Li, Hongjie,Li, Shasha,Zhang, Jinxia

, p. 9460 - 9473 (2019/08/26)

P,Nsp3-bidentate chiral ligands bearing spiro[indane-1,2′-pyrrolidine] backbone were prepared in gram scale for the first time. Pd complexes of these air-stable amino phosphine ligands could catalyze asymmetric allylic substitutions of malonate-, alcohol-, and amine-type nucleophiles in up to 97percent ee and 99percent yield. A crystal structure of [Pd(II)(η3-1,3-diphenylallyl)(ligand)]PF6 indicated possible transition states of the catalytic reactions. These ligands are characteristic of a very rigid backbone, which is simple but highly effective. They rival C2-symmetric bisphosphine, P,Nsp2-bidentate, and P,Nsp3-bidentate ligands in tested allylic substitutions. ?

Asymmetric synthesis of spiro 2-pyrrolidin-5-ones, 2-piperidin-6-ones and 1-isoindolin-3-ones. Part 1: N-acyliminium ion cyclisations with an internal arene nucleophile

Bahajaj, Abood A.,Moore, Madeleine H.,Vernon, John M.

, p. 1235 - 1246 (2007/10/03)

A series of chiral non-racemic 5,5- and 5,6-bicyclic lactams is prepared from (R)-phenylglycinol. These are isomerised on treatment with aluminium trichloride in 1,2-dichloroethane to give spiro lactams in high yield and >3:1 diastereoselectivity. From four structures determined by X-ray crystallography, it follows that spiro indenes are formed preferentially with retention of configuration at the spiro carbon atom and spiro naphthalenes with inversion.
