Check Digit Verification of cas no

The CAS Registry Mumber 1644257-88-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,2,5 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1644257-88:
(9*1)+(8*6)+(7*4)+(6*4)+(5*2)+(4*5)+(3*7)+(2*8)+(1*8)=184
184 % 10 = 4
So 1644257-88-4 is a valid CAS Registry Number.

Synthesis of spirocyclic enones by rhodium-catalyzed dearomatizing oxidative annulation of 2-alkenylphenols with alkynes and enynes

Kujawa, Szymon,Best, Daniel,Burns, David J.,Lam, Hon Wai

, p. 8599 - 8602 (2014/07/21)

The dearomatizing oxidative annulation of 2-alkenylphenols with alkynes and enynes proceeds with high yields and regioselectivities under RhIII catalysis. These reactions are successful using Cu(OAc)2 or air as the stoichiometric oxi
