330814-54-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 330814-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,8,1 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 330814-54:
(8*3)+(7*3)+(6*0)+(5*8)+(4*1)+(3*4)+(2*5)+(1*4)=115
115 % 10 = 5
So 330814-54-5 is a valid CAS Registry Number.

Synthesis of apicidin
Kuriyama, Wataru,Kitahara, Takeshi
, p. 1 - 4 (2007/10/03)
Tetrapeptide containing L-2-amino-8-protected hydroxydecanoic acid, L-N-O-methyltryptophan, L-isoleucine and D-pipecolinic acid was cyclized with pentafluorophenyl diphenylphosphinate. The cyclic tetrapeptide was deprotected and oxidized to apicidin [cyclo-(N-O-methyl-L-Trp-L-Ile-D-Pip-L-2-amino-8-oxo-decanoyl)].
