121221-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121221-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,2 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121221-95:
(8*1)+(7*2)+(6*1)+(5*2)+(4*2)+(3*1)+(2*9)+(1*5)=72
72 % 10 = 2
So 121221-95-2 is a valid CAS Registry Number.

Synthesis of Analogues of Arachidonic Acid as Potential Inhibitors of Leukotriene Biosynthesis
Buckle, Derek R.,Fenwick, Ashley E.
, p. 477 - 482 (2007/10/02)
A versatile route to 1,2-disubstituted aromatic analogues of arachidonic acid of formulae (5) and (6) has been established involving the stepwise cross-coupling of alkynes to 1,2-dibromobenzene.Subsequent reduction allows good control over the degree of u
