29471-17-8 Usage

Description

4′,4″(5″)-Di-tert-butyldibenzo-18-crown-6 is a hydrophobic crown ether compound. This crown ether is potentially useful in studies of ion transport through non-polar regions and membranes, and has been described in the design of microsensor devices for ammonia determination based upon ammonia-mediated deprotonation of a pH indicator followed by sequestering of ammonium within the 4′,4″(5″)-Di-tert-butyldibenzo-18-crown-6 sphere.

Chemical Properties

Off-white powder

Uses

4'',4''''(5'''')-Di-tert-butyldibenzo-18-crown-6 is a hydrophobic crown ether compound..

Check Digit Verification of cas no

The CAS Registry Mumber 29471-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,4,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29471-17:
(7*2)+(6*9)+(5*4)+(4*7)+(3*1)+(2*1)+(1*7)=128
128 % 10 = 8
So 29471-17-8 is a valid CAS Registry Number.
