Check Digit Verification of cas no
The CAS Registry Mumber 121221-88-3 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, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121221-88:
(8*1)+(7*2)+(6*1)+(5*2)+(4*2)+(3*1)+(2*8)+(1*8)=73
73 % 10 = 3
So 121221-88-3 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
