Check Digit Verification of cas no

The CAS Registry Mumber 634182-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,1,8 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 634182-03:
(8*6)+(7*3)+(6*4)+(5*1)+(4*8)+(3*2)+(2*0)+(1*3)=139
139 % 10 = 9
So 634182-03-9 is a valid CAS Registry Number.

Ir-catalyzed asymmetric hydrogenation of 3-arylindenones for the synthesis of chiral 3-arylindanones

Yan, Jun,Nie, Yu,Gao, Feng,Yuan, Qianjia,Xie, Fang,Zhang, Wanbin

, (2021/02/27)

An efficient synthesis of chiral 3-arylindanones via iridium-catalyzed asymmetric hydrogenation of 3-arylindenones has been developed. The reaction showed good compatibility with various functional groups, delivering a variety of 3-arylindanones in excellent yields and with good enantioselectivities. The reaction was also carried out on a gram-scale, delivering the product in quantitative yield. In addition, the products can be easily derivatized and transformed into natural products and pharmaceutical agents.

A palladium-catalyzed enantioselective reductive Heck reaction of enones using monodentate phosphoramidite ligands is described. α,α,α’,α’-tetraaryl-1,3-dioxolane-4,5-dimethanol (TADDOL)-based phosphoramidites with palladium(II) acetate, and N-methyl dicy

Palladium-catalyzed asymmetric reductive Heck reaction of aryl halides

Yue, Guizhou,Lei, Kaining,Hirao, Hajime,Zhou, Jianrong

supporting information, p. 6531 - 6535 (2015/06/08)

Asymmetric reductive Heck reaction of aryl halides is realized in high stereoselectivity. Hydrogen-bond donors, trialkylammonium salts in a glycol solvent, were used to promote halide dissociation from neutral arylpalladium complexes to access cationic, stereoselective pathways.
