Check Digit Verification of cas no

The CAS Registry Mumber 98451-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98451-39:
(7*9)+(6*8)+(5*4)+(4*5)+(3*1)+(2*3)+(1*9)=169
169 % 10 = 9
So 98451-39-9 is a valid CAS Registry Number.

Thermodynamic characteristics of the sorption of glycerol ethers on stationary phase OV-101

Zhabina,Krasnykh,Levanova

, p. 1590 - 1593 (2014/10/16)

Retention characteristics, temperature dependences of the retention characteristics, and thermodynamic characteristics of sorption on the nonpolar OV-101 phase are determined for 33 glycerol mono-, di-, and triethers with linear and branched monobasic alc

1-O-Alkyl (di)glycerol ethers synthesis from methyl esters and triglycerides by two pathways: Catalytic reductive alkylation and transesterification/reduction

Sutter, Marc,Dayoub, Wissam,Metay, Estelle,Raoul, Yann,Lemaire, Marc

supporting information, p. 786 - 797 (2013/04/24)

From available and bio-sourced methyl esters, monoglycerides or oleic sunflower refined oil, the corresponding 1-O-alkyl (di)glycerol ethers were obtained in both high yields and selectivity by two different pathways. With methyl esters, a reductive alkylation with (di)glycerol was realized under 50 bar hydrogen pressure in the presence of 1 mol% of Pd/C and an acid co-catalyst. A second two step procedure was evaluated from methyl esters or triolein and consisted of a first transesterification to the corresponding monoglyceride with a BaO/Al2O3 catalyst, then its reduction to the desired glycerol monoether with a recyclable heterogeneous catalytic system Pd/C and Amberlyst 35 under H2 pressure. In addition, a mechanism for the reaction was also proposed.

Selective synthesis of 1-O-Alkyl(poly)glycerol ethers by catalytic reductive alkylation of carboxylic acids with a recyclable catalytic system

Sutter, Marc,Dayoub, Wissam,Metay, Estelle,Raoul, Yann,Lemaire, Marc

, p. 2397 - 2409 (2013/02/23)

(Poly)glycerol monoethers were synthesized in good yield and selectivity by the catalytic reductive alkylation of glycerol, diglycerol, and triglycerol with readily available, cheap and/or bio-sourced carboxylic acids. The reaction was catalyzed by 1 mol % of Pd/C under 50 bar H2 using an acid ion-exchange resin as a recyclable cocatalyst. The catalytic system was recycled several times, and a mechanism is proposed for this transformation.

POLYOL ETHERS AND PROCESS FOR MAKING THEM

-

Paragraph 0093, (2011/05/14)

New polyol ether compounds and a process for their preparation. The process comprises reacting a polyol, a carbonyl compound, and hydrogen in the presence of hydrogenation catalyst, to provide the polyol ether. The molar ratio of polyol to carbonyl compound in the process is greater than 5:1.

PROCESS FOR MAKING POLYOL ETHERS
