209746-51-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 209746-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,7,4 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 209746-51:
(8*2)+(7*0)+(6*9)+(5*7)+(4*4)+(3*6)+(2*5)+(1*1)=150
150 % 10 = 0
So 209746-51-0 is a valid CAS Registry Number.

Synthesis and biological activities of some new fully fused quinazoline derivatives
Ibrahim,Abdel-Halim,Gabr,El-Edfawy,Abdel-Rahman
, p. 62 - 67 (2007/10/03)
Some fully fused quinazoline derivatives have been synthesized via condensation of 3-formylpyrazolo[5,1-b]quinazolin-9(1H)one 2 with bifunctional reagents followed by ring closure reactions. The structures of the products have been established by their el
