133210-64-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133210-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,1 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133210-64:
(8*1)+(7*3)+(6*3)+(5*2)+(4*1)+(3*0)+(2*6)+(1*4)=77
77 % 10 = 7
So 133210-64-7 is a valid CAS Registry Number.

Synthese de L'Hydroxy-9 Pyrimidopyrimidine one-4 et Derives
Dennin, F.,Blondeau, D.,Sliwa, H.
, p. 1963 - 1967 (2007/10/02)
Condensation of 5-alkoxy-4-aminopyrimidines with diethyl ethoxymethylenemalonate and with isopropylidene methoxymethylenemalonate, followed by thermal cyclization of the resulting enaminoesters intermediates yielded 9-alkoxypyrimidopyrimidin-4-ones
