Tris(hexafluoroacetylacetonato)gadolinium(III) dihydrate, also known as Gd(hfac)3·2H2O, is a gadolinium-based complex compound that is widely used as a contrast agent in magnetic resonance imaging (MRI). tris(hexafluoroacetylacetonato)gadolinium(III) dihydrate consists of a gadolinium(III) ion coordinated with three hexafluoroacetylacetonate (hfac) ligands and two water molecules. The gadolinium ion enhances the MRI signal, allowing for better visualization of tissues and organs. The hexafluoroacetylacetonate ligands provide stability to the complex, while the water molecules are present as a result of the compound's crystallization process. Overall, tris(hexafluoroacetylacetonato)gadolinium(III) dihydrate is a crucial component in medical imaging, particularly for detecting and diagnosing various diseases and conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 20558-32-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,5 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20558-32:
(7*2)+(6*0)+(5*5)+(4*5)+(3*8)+(2*3)+(1*2)=91
91 % 10 = 1
So 20558-32-1 is a valid CAS Registry Number.
