Check Digit Verification of cas no

The CAS Registry Mumber 892860-31-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,8,6 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 892860-31:
(8*8)+(7*9)+(6*2)+(5*8)+(4*6)+(3*0)+(2*3)+(1*1)=210
210 % 10 = 0
So 892860-31-0 is a valid CAS Registry Number.

A new type of ketolide bearing an N-aryl-alkyl acetamide moiety at the C-9 iminoether and its analogues were prepared, and their antibacterial activities and pharmacokinetic properties were evaluated. We found that the introduction of an (R)-alkyl group between the amide and iminoether groups could improve the pharmacokinetic properties while maintaining the activity against erythromycin-resistant Streptococcus pneumoniae. Among the ketolides prepared with the (R)-alkyl group, compound 5p with an N-(3-quinoxalin-6-yl-propyl)-propionamide moiety was found to have in vivo efficacy comparable to CAM with potent in vitro antibacterial activities against the key respiratory pathogens including Haemophilus influenzae and erythromycin-resistant S. pneumoniae.
