Check Digit Verification of cas no
The CAS Registry Mumber 142794-48-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,9 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142794-48:
(8*1)+(7*4)+(6*2)+(5*7)+(4*9)+(3*4)+(2*4)+(1*8)=147
147 % 10 = 7
So 142794-48-7 is a valid CAS Registry Number.

Catalytic Hydrogenation of Aryl Phosphines by Niobium Aryloxide Compounds: High Yield and Efficient Synthesis of Cyclohexyl Phosphine Ligands
Yu, Joyce S.,Rothwell, Ian P.
, p. 632 - 633 (1992)
The tris(4-methylbenzyl) compound Nb(OC6H3Ph2-2,6)2(CH2H4-4Me)3 1 (OC6H3Ph2-2,6 = 2,6-diphenylphenoxide) acts as a catalyst precursor for the hydrogenation of a variety of aryl phosphine ligands.
