Check Digit Verification of cas no

The CAS Registry Mumber 181657-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,6,5 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181657-29:
(8*1)+(7*8)+(6*1)+(5*6)+(4*5)+(3*7)+(2*2)+(1*9)=154
154 % 10 = 4
So 181657-29-4 is a valid CAS Registry Number.

Synthesis and biological evaluation of 4-alkoxy substituted trinems. Part 1

Andreotti, Daniele,Biondi, Stefano,Di Fabio, Romano,Donati, Daniele,Piga, Elisabetta,Rossi, Tino

, p. 2019 - 2024 (2007/10/03)

Synthesis of new 4-alkoxy substituted trinems 4, 5, 6, 7 and 8 together with their antibacterial profiles compared to imipenem and GV104326 (2) are described. The good antibacterial profile observed for derivatives 4-7 encouraged further exploration of these derivatives.
