643767-30-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 643767-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,6 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 643767-30:
(8*6)+(7*4)+(6*3)+(5*7)+(4*6)+(3*7)+(2*3)+(1*0)=180
180 % 10 = 0
So 643767-30-0 is a valid CAS Registry Number.

Nanomolar β-lactamase inhibitors
-
Page/Page column 39, (2010/11/28)
New carboxyphenyl-glycylboronic acid transition-state analog inhibitors, representative of a class of compounds effective against class C β-lactamase AmpC. The new compounds improve inhibition by over two-orders of magnitude compared to analogous glycylboronic acids, with Ki values as low as 1 nM.
