146443-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146443-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,4 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 146443-43:
(8*1)+(7*4)+(6*6)+(5*4)+(4*4)+(3*3)+(2*4)+(1*3)=128
128 % 10 = 8
So 146443-43-8 is a valid CAS Registry Number.

Synthesis of concave receptors derived from diphenylglycoluril
Sijbesma, R. P.,Nolte, R. J. M.
, p. 643 - 647 (2007/10/02)
Improved synthtic methods are described for the synthesis of concave receptor molecules.These receptors consist of a diphenylglycoluril unit, flanked by two aromatic moieties.The most versatile synthetic method consists of Lewis-acid-catalyzed reaction of
