880495-54-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 880495-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,4,9 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 880495-54:
(8*8)+(7*8)+(6*0)+(5*4)+(4*9)+(3*5)+(2*5)+(1*4)=205
205 % 10 = 5
So 880495-54-5 is a valid CAS Registry Number.

Synthesis of novel hantzsch dihydropyridine derivatives
Montazeri,Momeni,Pourshamsian,Dado
, p. 3415 - 3417 (2013/05/09)
A one-pot synthesis of novel Hantzsch dihydropyridine derivatives via a three-component cyclocondensation reaction of p-nitro acetoacetanilide, aromatic aldehyde and aqueous ammonia solution is presented. The protocol avoids the use of expensive catalyst,
