Check Digit Verification of cas no

The CAS Registry Mumber 52775-76-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,7 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 52775-76:
(7*5)+(6*2)+(5*7)+(4*7)+(3*5)+(2*7)+(1*6)=145
145 % 10 = 5
So 52775-76-5 is a valid CAS Registry Number.

Nucleotide sequence analysis reveals similarities between proteins determining methylenomycin A (cas 52775-76-5) resistance in Streptomyces and tetracycline resistance in eubacteria07/15/2019

Previous studies had localised the gene (mmr) for resistance to methylenomycin A (Mm) to a 2.5-kb PstI fragment in the middle of a cluster of Mm biosynthetic genes from the Streptomyces coelicolor plasmid SCP1. In this paper, the gene has been more precisely located by sub-cloning, and the nucle...detailed
