Calculate Digit Verification of CAS Registry Number 17816-68:
(7*1)+(6*7)+(5*8)+(4*1)+(3*6)+(2*6)+(1*8)=131
131 % 10 = 1
So 17816-68-1 is a valid CAS Registry Number.

Microwave-assisted solid-phase synthesis of 4,5-dihydroxy-1,3-dialkyl-4,5- diarylimidazolidine-2-thione and thiohydantoins

Ghanbari, Mohammad M.,Mahdavinia, Gholam H.,Safari, Javad,Naeimi, Hossein,Zare, Mehdi

experimental part, p. 2414 - 2420 (2011/08/05)

4,5-Dihydroxy-1,3-dialkyl-4,5-diarylimidazolidine-2-thione are obtained in good yields from the 1:1 addition reaction between benzil derivatives and thiourea derivatives in the solid phase. These compounds undergo smooth rearrangement followed by a hydrogen shift to produce thiohydantoins in excellent yields.
