2,6-bis-(diphenylphosphino)naphthalene, also known as 2,6-Bis(diphenylphosphino)naphthalene or abbreviated as DPPN, is a bidentate phosphine ligand widely used in homogeneous catalysis. It features a naphthalene core with two diphenylphosphino groups attached at the 2 and 6 positions, providing a rigid and planar structure. This ligand is known for its strong electron-donating properties and its ability to stabilize metal centers in various catalytic processes, such as olefin polymerization, hydrogenation, and cross-coupling reactions. DPPN's steric and electronic properties make it a valuable component in the design of catalysts that require high activity and selectivity.

Check Digit Verification of cas no

The CAS Registry Mumber 1182-02-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1182-02:
(6*1)+(5*1)+(4*8)+(3*2)+(2*0)+(1*2)=51
51 % 10 = 1
So 1182-02-1 is a valid CAS Registry Number.
