166761-48-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 166761-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,6,7,6 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 166761-48:
(8*1)+(7*6)+(6*6)+(5*7)+(4*6)+(3*1)+(2*4)+(1*8)=164
164 % 10 = 4
So 166761-48-4 is a valid CAS Registry Number.

Synthesis and characterization of heterobimetallic aryloxides of tantalum(V)

Chhipa, R. C.,Singh, A.,Mehrotra, R. C.

, p. 645 - 647 (2007/10/03)

Several new heterobimetallic aryloxides of tantalum(V) ofthe types MTa(OAr')6*2THF (1:M=K, Ar'=C6H3Me2-3,4; 2: M=K, Ar'=C6H3Me2-3,5; 3: M=K, Ar'=C6H2Me3-2,4,6; 4: M=Na, Ar'=C6H3Me2-3,5; 5: M=Na, Ar'=C6H4Cl-4 and 6: M=Li, Ar;=C6H4Cl-4) and TaAl(OAr';)8 (7: Ar'=C6H5; 8: Ar;=C6H4Bu'-4; 9: Ar'=C6H3Me2-3,5) have been synthesized and characterized by elemental analysis, spectroscopic (IR, 1H, 27Al NMR), molecular weight (ebullioscopic) and conductivity measurements.
