Check Digit Verification of cas no

The CAS Registry Mumber 890873-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,8,7 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 890873-89:
(8*8)+(7*9)+(6*0)+(5*8)+(4*7)+(3*3)+(2*8)+(1*9)=229
229 % 10 = 9
So 890873-89-9 is a valid CAS Registry Number.

New methodology for the N-alkylation of 2-amino-3-acylthiophenes

Aurelio, Luigi,Flynn, Bernard L.,Scammells, Peter J.

, p. 4886 - 4902 (2011)

2-Amino-3-acylthiophenes are known to allosterically modulate the A 1 adenosine receptor and are also used as intermediates in the synthesis of therapeutic agents and pharmacophores such as thienoazepines and thienopyrimidines. The N-alkylation
