105039-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 105039-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,0,3 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105039-51:
(8*1)+(7*0)+(6*5)+(5*0)+(4*3)+(3*9)+(2*5)+(1*1)=88
88 % 10 = 8
So 105039-51-8 is a valid CAS Registry Number.

Lithiophosphinoferrocenes. A route to polyphosphines and ring-substituted ferrocenophanes

Butler, Ian R.,Cullen, William R.

, p. 2537 - 2542 (2008/10/08)

The metalation of Fe(C5H4PPh2)(C5H5) (7) by n-BuLi affords predominantly hetero-ring dilithiated products 8 best characterized by their reaction with S8 which yields the [3]ferrocenophanes Fe(C5H3(P-(S)Ph2)S-1,n)(C5H 4S2) (n = 3 (?75%) or 2 (?25%). The PPh2 group has some effect in directing the metalation of 7 to the 2-position. Reaction of 8 with ClPPh2 affords tris (tertiary phosphines) and with Cl2PPh affords [1]ferrocenophanes such as Fe(C5H3(PPh2)PPh-1,3)(C5H 4) (12a). Cleavage of 12a with RLi takes place so that the anion is formed predominantly in the PPh2-substituted ring allowing the preparation of compounds such as Fe(C5H3(PPh2)SiMe3-1,3)(C 5H4PPhMe). Some arsenic derivatives and related chemistry of Fe(C5H4PPh2)2 are also described.
