409365-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 409365-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,9,3,6 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 409365-53:
(8*4)+(7*0)+(6*9)+(5*3)+(4*6)+(3*5)+(2*5)+(1*3)=153
153 % 10 = 3
So 409365-53-3 is a valid CAS Registry Number.

The synthesis and molecular structures of 2,5-diarylpyrroles, [pyr Ar2]H (Ar = Ph, 2,4-xyl)
Tanski, Joseph M.,Parkin, Gerard
, p. 185 - 190 (2007/10/03)
2,5-Di(2,4-xylyl)pyrrole, [pyr2,5-Xyl2]H, has been synthesized by reaction of the diketone [XylC(O)CH2]2 with NH 4OAc in AcOH; the diketone itself is obtained by condensation of XylC(O)Me with XylC(O)CH2/s
