Calculate Digit Verification of CAS Registry Number 944782-38:
(8*9)+(7*4)+(6*4)+(5*7)+(4*8)+(3*2)+(2*3)+(1*8)=211
211 % 10 = 1
So 944782-38-1 is a valid CAS Registry Number.

2-Alkyl-4-oxohexahydropyrimido[4,5-d]- and -[5,4-d]azocines

Voskressensky,Ovcharov,Borisova,Kulikova,Listratova,Borisov,Varlamov

, p. 222 - 228 (2011/12/15)

It has been established that 2-R-4-oxotetrahydropyrido[4,3-d]pyrimidines, under the action of activated alkynes in methanol, form a mixture of 2-R-4-oxohexahydropyrimido[4,5-d]azocines and products of decomposition of the tetrahydropyridine ring, the 2-R-5-methoxymethyl-4-oxo-6-vinylaminoethyl- pyrimidines. Tetrahydropyrido[3,4-d]pyrimidine, isomeric at the junction of the pyrimidine and tetrahydropyridine rings, forms only the corresponding pyrimido[5,4-d]azocine, the product of expansion, under the action of methyl propiolate.
