1405-98-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1405-98-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,0 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1405-98:
(6*1)+(5*4)+(4*0)+(3*5)+(2*9)+(1*8)=67
67 % 10 = 7
So 1405-98-7 is a valid CAS Registry Number.

-

Page/Page column 43; 44; 45, (2019/08/08)

The present invention relates to a catalytic process for the preparation of an ester starting from a carboxylic acid and an alkene using a zeolitic material having a BEA-type framework structure as the catalyst.

Efficient, stable, and reusable Lewis acid-surfactant-combined catalyst: One-pot Biginelli and solvent-free esterification reactions

Qiu, Yunfeng,Sun, Hongnan,Ma, Zhuo,Xia, Wujiong

, p. 76 - 82 (2014/06/10)

Cerium(III) trislaurylsulfonate (Ce(LS)3), a Lewis acid and surfactant combined catalyst, was prepared and characterized by SEM, SEM-EDX, XRD, NMR, FT-IR, TG, and elemental analysis. Ce(LS)3 was found to be stable and efficient to catalyze one-pot Biginelli and solvent-free esterification reactions. Furthermore, Ce(LS)3 is easy to recycle after reaction by pouring into cold water and filtration. Present work will shed deep insight into the understanding of the catalytic nature of LASCs, and extend its application in important organic transformations.
