1854-15-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1854-15-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,5 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1854-15:
(6*1)+(5*8)+(4*5)+(3*4)+(2*1)+(1*5)=85
85 % 10 = 5
So 1854-15-5 is a valid CAS Registry Number.

Ester Aminolysis in the Presence of Alkylammmonium Carboxylate Reversed Micelles. A Mechanistic Study

El Seoud, Omar A.,Vieira, Rita C.,Novaki, Luzia P.

, p. 1163 - 1164 (1987)

A study of ester aminolysis in the presence of dodecylammonium carboxylate reversed micelles showed that the catalytic role of the surfactant head-anion (general base) was concentration independent.The presence of co-solubilized water in the micelle did n

Facile preparation of amides from carboxylic acids and amines with ion-supported Ph3P

Kawagoe, Yuhsuke,Moriyama, Katsuhiko,Togo, Hideo

, p. 3971 - 3977 (2013/06/27)

Ion-supported Ph3P, 4-(diphenylphosphino)benzyltrimethylammonium bromide (IS-Ph3P), could be used for the facile amidation of a wide range of carboxylic acids with amines in the presence of bromotrichloromethane to provide the corresponding amides in good yields. In the present reaction, the desired amides were obtained in good yields with high purity by simple extraction of the reaction mixture with diethyl ether or chloroform and subsequent removal of the solvent from the extract. Moreover, ion-supported Ph3PO (IS-Ph3PO), which was a co-product derived from IS-Ph3P in the present reductive condensation, was recovered in high yield and could be reduced to IS-Ph3P for reuse in the same amidation of carboxylic acid.
