Calculate Digit Verification of CAS Registry Number 302926-41:
(8*3)+(7*0)+(6*2)+(5*9)+(4*2)+(3*6)+(2*4)+(1*1)=116
116 % 10 = 6
So 302926-41-6 is a valid CAS Registry Number.

Reaction of heterocyclic thioamides with dimethyl acetylenedicarboxylate. Synthesis of novel 2-azolyl-5-methoxycarbonylmethylene thiazolin-4-ones

Berseneva, Vera S,Morzherin, Yury Yu,Dehaen, Wim,Luyten, Ingrid,Bakulev, Vasiliy A

, p. 2179 - 2184 (2001)

A systematic study of the reactions of dimethyl acetylenedicarboxylate (DMAD) with heterocyclic thioamides has been carried out and a number of new 2-isoxazolyl-(8), imidazolyl-(13a,b and 17a), 1,2,3-triazolyl-(13d,e) and 1,2,3-thiadiazolyl (17b) thiazolines have been prepared. The higher reactivity of the thioamide group in comparison with the amino group in these reactions has been established.
