1042302-43-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1042302-43-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,3,0 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1042302-43:
(9*1)+(8*0)+(7*4)+(6*2)+(5*3)+(4*0)+(3*2)+(2*4)+(1*3)=81
81 % 10 = 1
So 1042302-43-1 is a valid CAS Registry Number.

Hydrogen-bonding in cyclic 2-(3-oxo-3-phenylpropyl)-substituted 1,3-diketones: 17O-NMR spectra and X-ray structure determination
Zhuo, Jin-Cong,Schenk, Kurt
, p. 1276 - 1283 (2007/10/03)
Structures of cyclic 2-(3-oxo-3-phenylpropyl)-substituted 1,3-diketones 4a-c were determined by 17O-NMR spectroscopy and X-ray crystallography. In CDCl3 solution, compounds 4a-c form an eight-membered-ring with intramolecular H-bondi
