Calculate Digit Verification of CAS Registry Number 140888-94:
(8*1)+(7*4)+(6*0)+(5*8)+(4*8)+(3*8)+(2*9)+(1*4)=154
154 % 10 = 4

Preparation of an angiotensin i analog containing a p-phosphonomethyl-l-phenylalanine residue via asymmetric synthesis of t-boc-p-dimethylphosphonomethyl-l-phenylalanine

Cushman, Mark,Lee, Eung-Seok

, p. 1193 - 1196 (1992)

t-BOC-p-Dimethylphoshonomethyl-L-phenylalanine has been prepared and incorporated into a peptide sequence corresponding to angiotensin I. Demethylation of the dimethylphosphonomethyl moiety then yielded a peptide containing a p-phosphonomethyl-L-phenylalanine residue.
