Check Digit Verification of cas no
The CAS Registry Mumber 158018-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,0,1 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 158018-53:
(8*1)+(7*5)+(6*8)+(5*0)+(4*1)+(3*8)+(2*5)+(1*3)=132
132 % 10 = 2
So 158018-53-2 is a valid CAS Registry Number.

Semisynthetic analogues of anhydrotetracycline as inhibitors of tetracycline destructase enzymes

The synthesis and biological evaluation of semisynthetic anhydrotetracycline analogues as small molecule inhibitors of tetracycline-inactivating enzymes are reported. Inhibitor potency was found to vary as a function of enzyme (major) and substrate-inhibitor pair (minor), and anhydrotetracycline analogue stability to enzymatic and nonenzymatic degradation in solution contributes to their ability to rescue tetracycline activity in whole cell Escherichia coli expressing tetracycline destructase enzymes. Taken collectively, these results provide the framework for the rational design of next-generation inhibitor libraries en route to a viable and proactive adjuvant approach to combat the enzymatic degradation of tetracycline antibiotics.
