139934-45-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139934-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139934-45:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*4)+(2*4)+(1*5)=165
165 % 10 = 5
So 139934-45-5 is a valid CAS Registry Number.

Extension of the hydrophobic cavity of calix[4]arene by 'upper rim' functionalization

Arduini,Pochini,Rizzi,Sicuri,Ugozzoli,Ungaro

, p. 905 - 912 (1992)

The hydrophobic cavity of calix[4]arene (1) has been extended by 'upper rim' functionalization with different alkyl groups. Using p-chloromethylcalix[4]arene (2) as the intermediate, the synthesis of ethyl (4) and p-benzylcalix[4]arenes (5 a-c) was performed. By reaction of 1 with cyclohexene p-cyclohexylcalix[4]arene (6) was obtained. The crystal structure of p-ethylcalix[4]arene (4) was solved.
