1126626-51-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1126626-51-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,6,6,2 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1126626-51:
(9*1)+(8*1)+(7*2)+(6*6)+(5*6)+(4*2)+(3*6)+(2*5)+(1*1)=134
134 % 10 = 4
So 1126626-51-4 is a valid CAS Registry Number.

Phosphines bearing alkyne substituents: Synthesis and hydrophosphination polymerization
Greenberg, Sharonna,Stephan, Douglas W.
, p. 8623 - 8631 (2010/01/06)
A synthetic route is described for a series of phosphines bearing pendant alkyne substituents, from the conversion of BrC6H2R 2C≡CR' (R = Me, i-Pr; R' = Ph, SiMe3) to [(μ-Br)Cu(Et2N)2PCsub
