Check Digit Verification of cas no

The CAS Registry Mumber 128886-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,8 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128886-84:
(8*1)+(7*2)+(6*8)+(5*8)+(4*8)+(3*6)+(2*8)+(1*4)=180
180 % 10 = 0
So 128886-84-0 is a valid CAS Registry Number.

Kinetic study on alkaline hydrolysis of Y-substituted phenyl X-substituted benzenesulfonates: Effects of changing nucleophile from azide to hydroxide ion on reactivity and transition-state structure

Moon, Ji-Hyun,Kim, Min-Young,Han, So-Yeop,Um, Ik-Hwan

, p. 1563 - 1568 (2015/08/11)

Second-order rate constants (kOH-) for alkaline hydrolysis of 2,4-dinitrophenyl X-substituted benzenesulfonates (1a-1f) and Y-substituted phenyl 4-nitrobezenesulfonates (2a-2g) have been measured spectrophotometrically. Comparison of kOH/

Design, synthesis, and insecticidal evaluation of new benzoylureas containing amide and sulfonate groups based on the sulfonylurea receptor protein binding site for diflubenzuron and glibenclamide

Sun, Ranfeng,Wang, Ziwen,Li, Yongqiang,Xiong, Lixia,Liu, Yuxiu,Wang, Qingmin

, p. 517 - 522 (2013/03/14)

On the basis of the sulfonylurea receptor (SUR) protein binding site for diflubenzuron and glibenclamide, 15 new benzoylphenylureas containing amide and sulfonate groups were designed and synthesized. Their structures were characterized by 1H n

Competitive Reaction Pathways in the Nucleophilic Substitution Reactions of Aryl Benzenesulfonates with Benzylamines in Acetonitrile

Choi, Jin Heui,Lee, Byung Choon,Lee, Hai Whang,Lee, Ikchoon

, p. 1277 - 1281 (2007/10/03)

The reactions of aryl benzenesulfonates (YC6H4SO2OC6H4Z) with benzylamines (XC6H4CH2NH2) in acetonitrile at 65.0 deg C have been studied. The reactons proceed competitevely by S-O (kS-O) and C-O (kC-O) bond scission, but the former provides the major reaction pathway. On the basis of analysis of the Hammet and Broensted coefficients together with the cross-interaction constants ρXY, ρYZ, and ρXZ, stepwise mechanisms are proposed in which the S-O bond cleavage proceeds by rate-limiting formation of a trigonal-bipyramidal pentacoordinate (TBP-5C) intermediate, whereas the C-O bond scission takes place by rate-limiting expulsion of the sulfonate anion (YC6H4SO3-) from a Meisenheimer-type complex.

Retardation of Hydrolysis of Aryl Arenesulphonate Esters by Quinuclidine through Complex Formation

Suh, Junghun,Suh,, Myung Koo,Cho, Seung Ho

, p. 685 - 688 (2007/10/02)

The hydrolysis of aryl arenesulphonate esters is considerably retarded upon the addition of quinuclidine (Quin).Kinetic and spectral data indicate that the protonated form of Quin forms non-covalent complexes with the sulphonate esters and that the comple
