Calculate Digit Verification of CAS Registry Number 137703-68:
(8*1)+(7*3)+(6*7)+(5*7)+(4*0)+(3*3)+(2*6)+(1*8)=135
135 % 10 = 5
So 137703-68-5 is a valid CAS Registry Number.

Tolstikov, G. A.,Shul'ts, E.E.,Safarova, G.M.,Spirikhin, L.V.,Panasenko, A.A.

, p. 1110 - 1119 (2007/10/02)

The diene synthesis reaction with the new highly active dienes 1-(2-furyl)- and (5-methyl-2-furyl)-3-trimethylsilyloxybutadienes and various dienophiles is a convenient method for the production of 2-furylcyclanones.It was established that the cycloaddition of the above-mentioned dienes to unsymmetrical dienophiles is highly regioselective.
