Check Digit Verification of cas no

The CAS Registry Mumber 10024-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,2 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 10024-57:
(7*1)+(6*0)+(5*0)+(4*2)+(3*4)+(2*5)+(1*7)=44
44 % 10 = 4
So 10024-57-4 is a valid CAS Registry Number.

Diacyl Disulfide: A Reagent for Chemoselective Acylation of Phenols Enabled by 4-(N,N-Dimethylamino)pyridine Catalysis

Liu, Hong-Xin,Dang, Ya-Qian,Yuan, Yun-Fei,Xu, Zhi-Fang,Qiu, Sheng-Xiang,Tan, Hai-Bo

, p. 5584 - 5587 (2016/11/17)

A general and excellent acylation reagent, diacyl disulfide, was uncovered for efficient ester formation enabled by DMAP (4-(N,N-dimethylamino)pyridine) catalysis. This protocol offered a promising synthetic platform on site-selective acylation of phenolic and primary aliphatic hydroxyl groups, which greatly expanded the realm of protecting group chemistry. The importance of the reagent was also reflected by its excellent moisture tolerance, high efficiency, and potential in synthetic chemistry and biologically meaningful natural product modification.

Effective Charge Development in Ester Hydrolysis Catalyzed by Cationic Micelles

Al-Awadi, Nouria,Williams, Andrew

, p. 2001 - 2004 (2007/10/02)

Reaction of hydroxide ion with substituted phenyl laurates is catalyzed by micelles containing CTAB (cetyltrimethylammonium bromide).The observed rate constants for ester consumption obey a Michaelis-Menten-like rate law, kobsd = (kOHKeq + kOHcat)/(Keq + ), where kOHcat is the second order rate constant for reaction of hydroxide ion with micelle-bound ester, Keq is a partition coefficient for dissociation of ester from the micelle-bound ester, and kOH is the second order rate constant for reaction of free ester with hydroxide ion.The value of the parameter Keq is independent of the nature of the substituent on the ester.The ratio kOHcat/Keq represents the free energy change from ester in aqueous solution to the transition state of the ester reaction in the micellar pseudophase.The dependence of log kOHcat/Keq on the pKa of the leaving phenol obeys a linear Bronsted equation with β1g = -0.51, and log kOH obeys a linear Bronsted equation with β1g = -0.56.Since both Bronsted parameters refer to catalyzed and uncatalyzed reactions starting from the same standard state (aqueous solution), the effective charge in the transtition state of both reactions is almost the same.The microscopic medium is thus similar for both cases, consistent with the COOAr moiety's residing in an aqueous-like region of the pseudophase in the catalytic process.
