150417-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 150417-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,4,1 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 150417-69:
(8*1)+(7*5)+(6*0)+(5*4)+(4*1)+(3*7)+(2*6)+(1*9)=109
109 % 10 = 9
So 150417-69-9 is a valid CAS Registry Number.

Two new antibiotics from the Red Sea sponge Psammaplysilla purpurea. Total 13C-NMR line assignment of psammaplysins A and B and aerothionin
Rotem,Carmely,Kashman,Loya
, p. 667 - 676 (2007/10/02)
Two new tetra bromo metabolites (3 and 4), possessing the hitherto unknown spirocyclohexadienyloxazoline moiety, have been isolated from the sponge Psammaplysilla purpurea. The structure of compounds 3 and 4 have been elucidated by using spectroscopic met
