156618-45-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156618-45-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,1 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156618-45:
(8*1)+(7*5)+(6*6)+(5*6)+(4*1)+(3*8)+(2*4)+(1*5)=150
150 % 10 = 0
So 156618-45-0 is a valid CAS Registry Number.

New C2-chiral bidentate ligands bridging the gap between donor phosphine and acceptor carbonyl ligands
Kundig,Dupre,Bourdin,Cunningham Jr.,Pons
, p. 421 - 428 (1994)
Two new C2 chiral bidentate phosphorous ligands have been prepared in enantiomerically pure form. The two phosphorous centers bear electron-withdrawing groups ((CF3)2CH-O, C6F5) and are linked by a tr
