136121-21-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136121-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,1,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136121-21:
(8*1)+(7*3)+(6*6)+(5*1)+(4*2)+(3*1)+(2*2)+(1*1)=86
86 % 10 = 6
So 136121-21-6 is a valid CAS Registry Number.

Hydrazino and N-Amino peptides. Chemical and structural aspects
Lecoq, Alain,Marraud, Michel,Aubry, Andre
, p. 2765 - 2768 (2007/10/02)
The regioselective acylation of the nitrogens in hydrazino acetic acid has been studied to obtain the hydrazide and N-amino amide peptidomimetic groups Their conformational influence on the β-turn structure has also been considered.
