54164-89-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54164-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,6 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54164-89:
(7*5)+(6*4)+(5*1)+(4*6)+(3*4)+(2*8)+(1*9)=125
125 % 10 = 5
So 54164-89-5 is a valid CAS Registry Number.

Biomimetic conversion of α-pinene with H2O2 to sobrerol over V2O5: Dihydroxylation by a peroxo vanadium peracid vectoring gentle synergistic oxidation

He, Huiting,Huang, Geng,Kirk, Steven Robert,Li, Hui,Liu, Jian,Liu, Qiang,Liu, Xianxiang,Mao, Liqiu,Su, Shengpei,Xu, Qiong,Yin, Dulin

, (2020/05/18)

In this communication, we report the gentle preparation of sobrerol from dihydroxylation of α-pinene synergistically catalyzed by V2O5-H2O2 under benign conditions. It was proposed that a “peroxo vanadium acid”, VVO(OH)(OOH), was formed by HOO? insertion and proton transfer between V2O5 and H2O2. Theoretical DFT calculations that using the dimer?vanadium peracid as a model of the catalytically active species revealed that peroxo vanadium acid exhibited bifunctional catalytic capabilities resembling epoxidation of α-pinene by peracetic acid and then open-ring hydration with an acetic media.

Unique salt effect on highly selective synthesis of acid-labile terpene and styrene oxides with a tungsten/Hcatalytic system under acidic aqueous conditions

Hachiya, Houjin,Kon, Yoshihiro,Ono, Yutaka,Takumi, Kiyoshi,Sasagawa, Naoki,Ezaki, Yoichiro,Sato, Kazuhiko

experimental part, p. 1672 - 1678 (2012/07/16)

Acid-labile epoxides such as terpene and styrene oxides are effectively synthesized in high yields with good selectivities using tungsten-catalyzed hydrogen peroxide epoxidation in the presence of NaO The salt effect is thought to originate with the addition of a saturated amount of NaOto aqueous H this addition strongly inhibited the undesired hydrolysis of the acid-labile epoxy products, despite the biphasic conditions of substrate as oil phase and Has acidic aqueous phase.

Comparative autoxidation of 3-Carene and α-Pinene: Factors governing regioselective hydrogen abstraction reactions

Rothenberg, Gadi,Yatziv, Yael,Sasson, Yoel

, p. 593 - 598 (2007/10/03)

Autoxidation reactions of 3-Carene 1 and α-Pinene 2 were performed using various homogeneous catalysts. Different product and regio- selectivities were observed. The factors that promote hydrogen abstraction (HA) reactions in both molecules are discussed, and it is proposed that the difference in the product selectivities is due to the lack of 'cyclic activation' in 2. Oxidation of 1 produced mainly 3-carene-5-one 3, while 2 yielded 2,3-epoxypinane 6 as the major product.
