137767-81-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137767-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,6 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137767-81:
(8*1)+(7*3)+(6*7)+(5*7)+(4*6)+(3*7)+(2*8)+(1*1)=168
168 % 10 = 8
So 137767-81-8 is a valid CAS Registry Number.

Biosynthesis of Neocarazostatin A Reveals the Sequential Carbazole Prenylation and Hydroxylation in the Tailoring Steps

Neocarazostatin A (NZS) is a bacterial alkaloid with promising bioactivities against free radicals, featuring a tricyclic carbazole nucleus with a prenyl moiety at C-6 of the carbazole ring. Here, we report the discovery and characterization of the biosynthetic pathway of NZS through genome mining and gene inactivation. The in vitro assays characterized two enzymes: NzsA is a P450 hydroxylase and NzsG is a new phytoene-synthase-like prenyltransferase (PTase). This is the first reported native PTase that specifically acts on the carbazole nucleus. Finally, our in vitro reconstituted experiment demonstrated a coupled reaction catalyzed by NzsG and NzsA tailoring the NZS biosynthesis.
