89088-28-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89088-28-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,8 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89088-28:
(7*8)+(6*9)+(5*0)+(4*8)+(3*8)+(2*2)+(1*8)=178
178 % 10 = 8
So 89088-28-8 is a valid CAS Registry Number.

Synthesis of Dihydromauritine A, a Reduced Cyclopeptide Alkaloid
Nutt, Ruth F.,Chen, Kau-Ming,Jouille, Madeleine M.
, p. 1013 - 1021 (2007/10/02)
The synthesis of the strained 14-membered cyclopeptide alkaloid derivative dihydromauritine A has been accomplished from L-proline via SN2 displacement and three amide bond forming steps.The nucleophilic displacement involved a β-bromopyrroline
