Check Digit Verification of cas no

The CAS Registry Mumber 1427217-92-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,1 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1427217-92:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*1)+(3*7)+(2*9)+(1*2)=152
152 % 10 = 2
So 1427217-92-2 is a valid CAS Registry Number.

Synthesis of 1,1′,2-trisubstituted aryl-based ferrocenyl phosphines as precursors for immobilized ligands

Madalska, Martyna,Loennecke, Peter,Ivanovski, Vladimir,Hey-Hawkins, Evamarie

, p. 5852 - 5861 (2013/11/19)

Ferrocenylaryl or ferrocenylheteroaryl phosphines bearing a carboxaldehyde group, [Fe{1-PPh2(spacer)-2-NMe2CH2C 5H3}(C5H4CHO)] (spacer = none (rac-12), 1,4-phenylene (rac-13), 1,3-phenylene (rac-14), 2,5-thienylene (rac-15)), were prepared in a facile four-step sequence starting with dibromination of N,N-dimethylaminomethylferrocene (1) followed by Negishi cross-coupling between 1,1′-dibromo-2-N,N-dimethylaminomethylferrocene (rac-2) and aryl or heteroaryl bromide phosphine oxides, Br-spacer-P(O)Ph 2 (spacer = 1,4-phenylene, 1,3-phenylene, 2,5-thienylene), reduction with trichlorosilane, and functionalization of the 1′-position of the cyclopentadienyl ring. All products were fully characterized by spectroscopy (1H, 13C, and 31P NMR, MS, IR) and for rac-3, rac-7 and rac-11 also by X-ray crystallography. Furthermore, preliminary studies on the grafting of rac-12 on silica were conducted.
