1154733-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1154733-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,4,7,3 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1154733-23:
(9*1)+(8*1)+(7*5)+(6*4)+(5*7)+(4*3)+(3*3)+(2*2)+(1*3)=139
139 % 10 = 9
So 1154733-23-9 is a valid CAS Registry Number.

Fluorescent carbazolylurea anion receptors
Hiscock, Jennifer R.,Caltagirone, Claudia,Light, Mark E.,Hursthouse, Michael B.,Gale, Philip A.
, p. 1781 - 1783 (2009)
A series of fluorescent carbazolylurea base anion receptors have been synthesised that show a high affinity for oxo-anions (particularly bicarbonate and acetate). The fluorescence of dicarbazolylurea (1) is quenched upon addition of benzoate anions in DMS
