Check Digit Verification of cas no
The CAS Registry Mumber 127902-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,0 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127902-98:
(8*1)+(7*2)+(6*7)+(5*9)+(4*0)+(3*2)+(2*9)+(1*8)=141
141 % 10 = 1
So 127902-98-1 is a valid CAS Registry Number.

Streamlined synthesis of (R, R)-rhizoferrin, (S, S)-rhizoferrin and (R, S, R)-staphyloferrin A

(R, R)-Rhizoferrin and (R, S, R)-staphyloferrin A are carboxylate-type siderophores. Their streamlined synthesis has been accomplished starting from (R)-citric acid. Key-step of these syntheses is a chemo-enzymatic ester hydrolysis. (S, S)-rhizoferrin was accessible by a multistep synthesis starting from an (S)-citrate derived synthon.
