Check Digit Verification of cas no

The CAS Registry Mumber 1254367-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,3,6 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1254367-89:
(9*1)+(8*2)+(7*5)+(6*4)+(5*3)+(4*6)+(3*7)+(2*8)+(1*9)=169
169 % 10 = 9
So 1254367-89-9 is a valid CAS Registry Number.

8-azatetracyclines: Synthesis and evaluation of a novel class of tetracycline antibacterial agents

Clark, Roger B.,He, Minsheng,Fyfe, Corey,Lofland, Denene,O'Brien, William J.,Plamondon, Louis,Sutcliffe, Joyce A.,Xiao, Xiao-Yi

experimental part, p. 1511 - 1528 (2011/05/05)

A novel series of fully synthetic 8-azatetracyclines was prepared and evaluated for antibacterial activity. Compounds were identified that overcome both efflux (tet(K)) and ribosomal protection (tet(M)) tetracycline resistance mechanisms and are active against Gram-positive and Gram-negative organisms. Two compounds were identified that exhibit comparable efficacy to marketed tetracyclines in in vivo models of bacterial infection.
