118854-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118854-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,8,5 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118854-40:
(8*1)+(7*1)+(6*8)+(5*8)+(4*5)+(3*4)+(2*4)+(1*0)=143
143 % 10 = 3
So 118854-40-3 is a valid CAS Registry Number.

Orbital control in the reductive cleavage of tris(methoxyphenyl)phosphines
Budzelaar, Peter H. M.,Doorn, Johannes A. van,Meijboom, Nico
, p. 253 - 254 (2007/10/02)
The character of the LUMO of (methoxyphenyl)phosphines determines the reductive cleavage of the C-P bond; a high LUMO energy prevents reduction whereas a small coefficient at the C-P carbon atom leads to a poor cleavage.
