Calculate Digit Verification of CAS Registry Number 4526-87:
(6*4)+(5*5)+(4*2)+(3*6)+(2*8)+(1*7)=98
98 % 10 = 8
So 4526-87-8 is a valid CAS Registry Number.

ONE-POT CYCLIZATION OF A PEPTIDE BY THE USE OF (5-NITROPYRIDYL)DIPHENYL PHOSPHINATE: THE SYNTHESIS OF CYCLIC DECAPEPTIDE GRAMICIDIN S

Mukaiyama, Teruaki,Kamekawa, Kenichi,Watanabe, Yutaka

, p. 1367 - 1370 (2007/10/02)

One-pot synthesis of gramicidin S, cyclic decapeptide, was successfully achieved by treatment of the corresponding linear decapeptide with (5-nitropyridyl)diphenyl phosphinate, a new condensing reagent, in pyridine.Similarly, the phosphinic ester can be successfully employed in the Young test as well as syntheses of dipeptides.
