142733-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142733-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,3 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142733-55:
(8*1)+(7*4)+(6*2)+(5*7)+(4*3)+(3*3)+(2*5)+(1*5)=119
119 % 10 = 9
So 142733-55-9 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 (2007/10/02)
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.
