93503-76-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93503-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,0 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93503-76:
(7*9)+(6*3)+(5*5)+(4*0)+(3*3)+(2*7)+(1*6)=135
135 % 10 = 5
So 93503-76-5 is a valid CAS Registry Number.

Synthesis of p-alkylcalixarenes by Friedel-Crafts alkylation
Zheng, Yan-Song,Huang, Zhi-Tang
, p. 1237 - 1245 (2007/10/03)
Calix[n]arenes 1-3 (n = 4, 6 and 8) were alkylated with alkyl chlorides in the presence of anhydrous aluminium chloride in chloroform by Friedel-Crafts reaction to give p-alkylcalix[n]arens 5-7 (n = 4, 6 and 8) in good to excellent yields.
