Check Digit Verification of cas no

The CAS Registry Mumber 39587-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,8 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39587-22:
(7*3)+(6*9)+(5*5)+(4*8)+(3*7)+(2*2)+(1*2)=159
159 % 10 = 9
So 39587-22-9 is a valid CAS Registry Number.

Efficient concrete foam stabilizer and preparation method thereof

-

Paragraph 0027; 0043-0044, (2021/07/17)

The invention discloses an efficient concrete foam stabilizer and a preparation method thereof, according to the efficient foam stabilizer, polyol is subjected to an esterification reaction to form ester bonds, and the ester bonds are connected with amphiphilic side chains, and the number of the amphiphilic side chains is 3-7; one end of the amphiphilic side chain is a hydrophobic chain segment, and the other end of the amphiphilic side chain is a hydrophilic unit; wherein the hydrophobic chain segment is an alkyl chain (R) with 8-14 carbons, and the hydrophilic unit is 2-10 ethylene oxide units. The efficient concrete foam stabilizer is a multi-chain type surfactant, and the multi-chain type surfactant is hydrolyzed under the alkaline condition to release an air-entraining type surfactant. The efficient concrete foam stabilizer has an excellent effect of stabilizing the air content of concrete, meanwhile, hardened concrete has a better pore structure, and the hardening strength of the concrete cannot be greatly influenced.

Synthesis of some acyclic quaternary ammonium compounds. Alkylation of secondary and tertiary amines in a two-phase system

Kharlamov,Artyushin,Bondarenko

, p. 2445 - 2454 (2015/08/03)

A series of acyclic symmetrical and asymmetrical quaternary ammonium chlorides of the general formula R1R2R3N+AR4Cl- (R1 = Me, Bu; R2 = n-C12H25, PhCH2, C n H2n+1(OCH2CH2) m, n = 9 and 12, m = 1 and 2; R3 = n-C12H25, PhCH2, HOCH2CH2,-OOCCH2; R4 = n-C12H25, PhCH2; A = (CH2CH2O)1,2, CH2C(O)O) was synthesized by the alkylation of tertiary amines in a two-phase system containing water. A convenient method for the synthesis of the initial symmetrical and asymmetrical tertiary amines of the general formula MeNR1R2 (R1 = Me, Bu; R2 = n-C12H25, PhCH2, CnH2n+1(OCH2CH2) m, n = 9 and 12, m = 1 and 2) in an organic phase-aqueous phase heterogeneous system, which allows the use of aqueous solutions of alkali and amines, was developed. The improved method for the preparation of intermediate ethylene glycol and diethylene glycol monoethers is monoalkylation of glycols in dioxane using solid KOH in a two-phase system.
