89558-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89558-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,5 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89558-11:
(7*8)+(6*9)+(5*5)+(4*5)+(3*8)+(2*1)+(1*1)=182
182 % 10 = 2
So 89558-11-2 is a valid CAS Registry Number.

REACTION OF A DIPHOSPHENE WITH BUTYLLITHIUM
Yoshifuji, Masaaki,Shibayama, Katsuhiro,Inamoto, Naoki
, p. 115 - 118 (2007/10/02)
1,2-Bis(2,4,6-tri-t-butylphenyl)diphosphene reacted with butyllithium to give 1-alkyl-2-butyl-1,2-bis(2,4,6-tri-t-butylphenyl)diphosphanes after quenching with various alkyl halides, sulfurization of which afforded diphosphane monosulfides.
