65745-83-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65745-83-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,7,4 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65745-83:
(7*6)+(6*5)+(5*7)+(4*4)+(3*5)+(2*8)+(1*3)=157
157 % 10 = 7
So 65745-83-7 is a valid CAS Registry Number.

Synthesis of macrocyclic polyether-diester compounds using Al2O3/MeSO3H (AMA) as a new reagent

Sharghi, Hashem,Sarvari, Mona Hosseini

, p. 879 - 882 (2007/10/03)

A new simple and convenient method for the synthesis of macrocyclic polyether-diester compounds containing pyridine and phenyl subcyclic units is developed. Various diacids, are selectively esterified in excellent yields by reaction with oligoethylene glycols in the presence of Al2O3/MeSO3H (AMA) as a new reagent without use of any solvents.

THE PREPARATION OF MACROCYCLIC DI- OR TETRAESTER/ETHER COMPOUNDS FROM GLYCOLS WITH DIACID CHLORIDES BY THE USE OF DIBUTYLTIN OXIDE

Ninagawa, Akira,Maeda, Takeshi,Matsuda, Haruo

, p. 1985 - 1988 (2007/10/02)

Several macrocyclic di- or tetraester/ether compounds were readily prepared by reacting various oligoethylene glycols with aliphatic and aromatic diacid chlorides, and hetero atoms-containing diethylene glycols with adipoyl chloride by the use of dibutyltin oxide in good yields.
