Check Digit Verification of cas no
The CAS Registry Mumber 518-90-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 518-90:
(5*5)+(4*1)+(3*8)+(2*9)+(1*0)=71
71 % 10 = 1
So 518-90-1 is a valid CAS Registry Number.

A series of C-3' ortho dihydroxyphthalimido cephalosporins 3~7 has been prepared by reaction of C-3' aminomethyl cephalosporin 411) with the corresponding N carboethoxyphthalimides 23 ~ 25, 37, 38. These new caphalosporins exhibit excellent in vitro Gram-negative activities, including Pseudomonas aeruginosa, excellent β-lactamases stability and pharmacokinetics equivalent or better than ceftriaxone.
