Check Digit Verification of cas no

The CAS Registry Mumber 126306-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,0 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126306-29:
(8*1)+(7*2)+(6*6)+(5*3)+(4*0)+(3*6)+(2*2)+(1*9)=104
104 % 10 = 4
So 126306-29-4 is a valid CAS Registry Number.

Reaktionen koordinierter Liganden V. Pentacarbonylhalogenaminophosphinkomplexe (CO)5MPRXNR'2 durch Umsetzung von (CO)5MPR(NR'2)2 mit Halogenwasserstoff

Diemert, K.,Kuchen, W.,Lorenzen, D.

, p. 17 - 32 (1989)

Aminophosphines RP(NR'2)2 (R = Ph, cyclo-Hex, (-)-Men, t-Bu; R' = Me, Et) as ligands L in complexes (CO)5ML (M = Cr, Mo, W) have been found to react with HX (X = Cl, Br) mainly under substitution of only one of the two dialkylamino groups by halogen.Under similar conditions the free phosphines are converted into the dihalogenphosphines.The halogenamino complexes (CO)5MPRXNR'2 are readily accessible by this reaction, the mechanism of which is discussed.The preparation of several new compounds RP(NR'2)2 is reported.
