61539-20-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61539-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,5,3 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 61539-20:
(7*6)+(6*1)+(5*5)+(4*3)+(3*9)+(2*2)+(1*0)=116
116 % 10 = 6
So 61539-20-6 is a valid CAS Registry Number.

Tricyclic 6-alkylidene-penems as class-D beta-lactamases inhibitors
-
Page/Page column 28, (2010/11/25)
This invention relates to certain tricyclic 6-alkylidene penems which act as a inhibitor of class-D enzymes. β-Lactamases hydrolyze β-lactam antibiotics, and as such serve as the primary cause of bacterial resistance. The compounds of the present inventio
