197796-03-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197796-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,9 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197796-03:
(8*1)+(7*9)+(6*7)+(5*7)+(4*9)+(3*6)+(2*0)+(1*3)=205
205 % 10 = 5
So 197796-03-5 is a valid CAS Registry Number.

Head-to-Tail Connected Double Calix[4]arenes

Wasikiewicz,Rokicki,Kielkiewicz,Paulus,Boehmer

, p. 863 - 879 (1997)

New macrotricyclic compounds consisting of two calix[4]arene substructures connected by aliphatic chains of various length (three to five carbon atoms) between two opposite p-positions and two distal phenolic oxygens have been synthesized. Starting with p-tert-butyl-calix[4]arene, two O-protected phenolic units are attached via ether links in 1,3-position by reaction with the corresponding tosylates. After deprotection, the new calix[4]arene is formed by fragment condensation with 2,6-tobromomethylated 4-alkylphenols. The structure of one example (8c) has been confirmed by single crystal X-ray analysis. Both calixarene parts assume the cone conformation, a molecule of acetonitrile being included in both cavities.
