251096-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 251096-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,0,9 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 251096-27:
(8*2)+(7*5)+(6*1)+(5*0)+(4*9)+(3*6)+(2*2)+(1*7)=122
122 % 10 = 2
So 251096-27-2 is a valid CAS Registry Number.

A novel access to alicyclic phosphine oxides via ring closing metathesis
Trevitt,Gouverneur
, p. 7333 - 7336 (2007/10/03)
A series of cyclic phosphine oxides 5a-e was prepared in a one-step procedure by RCM of dienes 4a-e. The methodology was extended to the preparation of the bis-phosphine oxide 5f.
