141914-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141914-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,1 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141914-54:
(8*1)+(7*4)+(6*1)+(5*9)+(4*1)+(3*4)+(2*5)+(1*4)=117
117 % 10 = 7
So 141914-54-7 is a valid CAS Registry Number.

Synthesis and Structure of a New Type of Polycyclic Peptide
Bailey, Patrick D.,Clarke, David G. W.,Crofts, Gavin A.
, p. 658 - 660 (2007/10/02)
The synthesis of a 'polycyclic peptide' is described, in which the ε-nitrogens of cyclo-(Lys-Lys-Gly)2 are interconnected by four p-xylyl moieties; this is the first example of the use of multiple cross-linking to generate highly constrained peptides, and
