Check Digit Verification of cas no

The CAS Registry Mumber 25226-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,2 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25226-45:
(7*2)+(6*5)+(5*2)+(4*2)+(3*6)+(2*4)+(1*5)=93
93 % 10 = 3
So 25226-45-3 is a valid CAS Registry Number.

Reductive elimination of halogens assisted by phosphine ligands in Fe(CO)4X2 (X = I, Br) complexes

Bellachioma, Gianfranco,Cardaci, Giuseppe,Macchioni, Alceo,Venturi, Chiara,Zuccaccia, Cristiano

, p. 3881 - 3888 (2007/10/03)

Fe(CO)4X2 complexes [X = I (1), Br(1′)] react with phosphine ligands L (L = PMe3, PEt3, PMe2Ph, PMePh2, PPh3) via a two-step mechanism: in the first step fac-Fe(CO)3LX2 complexes are formed; in the second step two parallel pathways, a and b, are observed; in pathway a, reductive elimination with formation of equimolar amounts of Fe(CO)3L2 (5) and phosphonium salts [LX]+X- is observed; in pathway b, disubstituted dihalide complexes cis,trans,cis-Fe(CO)2L2X2 are formed. The relative weights of pathways a and b depend on the basicity, steric hindrance and concentration of ligand L, on the nature of the halogen and on temperature. A radical mechanism which accounts for most of the experimental results is proposed.
