Check Digit Verification of cas no

The CAS Registry Mumber 69320-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,3,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69320-90:
(7*6)+(6*9)+(5*3)+(4*2)+(3*0)+(2*9)+(1*0)=137
137 % 10 = 7
So 69320-90-7 is a valid CAS Registry Number.

Total Synthesis of Seongsanamide B

Hutton, Craig A.,Shabani, Sadegh

, (2020)

The first total synthesis of the bicyclic depsipeptide natural product seongsanamide B is described. The successful approach employed solid-phase peptide synthesis of a core heptapeptide, incorporating on-resin esterification, followed by solution-phase macrolactamization and a late stage intramolecular Evans-Chan-Lam coupling to generate the biaryl ether of the isodityrosine unit.
