Check Digit Verification of cas no
The CAS Registry Mumber 257277-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,2,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 257277-40:
(8*2)+(7*5)+(6*7)+(5*2)+(4*7)+(3*7)+(2*4)+(1*0)=160
160 % 10 = 0
So 257277-40-0 is a valid CAS Registry Number.

Sodium 7β[(R)-2(N(b)-o-nitrobenzyloxycarbonyl)hydrazino-3- phenylpropanamido]cephalosporanate (1) is described as a new type of β- lactam antibiotic, which undergoes light-induced destruction of its β-lactam moiety and hence becomes biologically inactive.
