μ-Carbonyl-dicarbonylbis(η5-cyclopentadienyl)(μ-phenylisocyanide)diiron is a complex organometallic compound with the chemical formula C21H13Fe2NO2. It consists of two iron atoms, each coordinated to a cyclopentadienyl ligand (η5-C5H5), and a phenylisocyanide ligand bridging the two iron centers. The compound also features two carbonyl groups (CO) and a μ-carbonyl group connecting the two iron atoms. This molecule is an example of a sandwich complex, where the metal atoms are "sandwiched" between the cyclopentadienyl ligands. It is known for its unique structure and potential applications in catalysis and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 12149-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,4 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12149-07:
(7*1)+(6*2)+(5*1)+(4*4)+(3*9)+(2*0)+(1*7)=74
74 % 10 = 4
So 12149-07-4 is a valid CAS Registry Number.
