296244-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 296244-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,6,2,4 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 296244-43:
(8*2)+(7*9)+(6*6)+(5*2)+(4*4)+(3*4)+(2*4)+(1*3)=164
164 % 10 = 4
So 296244-43-4 is a valid CAS Registry Number.

Synthesis of spiroheterocyclic systems from barbituric acids and N,N-disubstituted o-aminobenzaldehydes
Krasnov,Kartsev
, p. 901 - 906 (2007/10/03)
Reactions of barbituric, 1,3-dimethylbarbituric, and 2-thiobarbituric acids with 2-(1-pyrrolidinyl)benzaldehyde, its 6- and 7-membered homologs, and 4-phenylpiperazine and morpholine analogs lead to formation of fused systems with a spirocyclic 2,4,6-trio
