189884-53-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189884-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,8 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189884-53:
(8*1)+(7*8)+(6*9)+(5*8)+(4*8)+(3*4)+(2*5)+(1*3)=215
215 % 10 = 5
So 189884-53-5 is a valid CAS Registry Number.

Highly Regio- A nd Enantioselective Hydrogenation of Conjugated α-Substituted Dienoic Acids

Liu, Xian,Liu, Song,Wang, Quanjun,Zhou, Gang,Yao, Lin,Ouyang, Qin,Jiang, Ru,Lan, Yu,Chen, Weiping

, p. 3149 - 3154 (2020/04/09)

Highly regio- A nd enantioselective hydrogenation of conjugated α-substituted dienoic acids was realized for the first time using Trifer-Rh complex, providing a straightforward method for the synthesis of chiral α-substituted ?,?′-unsaturated acids. DFT calculations revealed N+H-O hydrogen bonding interaction is formed to stabilize the transition state and the coordination of 4,5-double bond to Rh(III) center would facilitate the reductive elimination process. This hydrogenation provided a gram-scale synthesis of the precursor of sacubitril.

Retention of regiochemistry of monosubstituted allyl acetates in the ruthenium catalysed allylic alkylation with malonate anion

Kawatsura, Motoi,Ata, Fumio,Hayase, Shuichi,Itoh, Toshiyuki

, p. 4283 - 4285 (2008/03/28)

In the RuCl2(p-cymene)/PPh3 catalysed regioselective allylic alkylation of monosubstituted allyl acetates with malonate anion, the selective substitution at the position originally substituted with acetate was observed. The Royal Society of Chemistry.

Synthetic studies on (+)-ophiobolin A: Asymmetric synthesis of the spirocyclic CD-ring moiety

Noguchi, Naoyoshi,Nakada, Masahisa

, p. 2039 - 2042 (2007/10/03)

Asymmetric synthesis of the spirocyclic CD-ring moiety of (+)-ophiobolin A is described. Fragment A, which was prepared via pig liver esterase (PLE)-mediated kinetic resolution, and fragment B, which was prepared via diastereoselective allylation and subs
