1422156-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422156-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,1,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1422156-87:
(9*1)+(8*4)+(7*2)+(6*2)+(5*1)+(4*5)+(3*6)+(2*8)+(1*7)=133
133 % 10 = 3
So 1422156-87-3 is a valid CAS Registry Number.

, p. 112 - 120 (2013/02/25)
Based on the β-turn preference of tetrapeptide sequences as analyzed by CD spectra of their chromophoric derivatives, 10 analogs of gramicidin S (GS) were designed and synthesized with general formula cyclo(D- Leu1,1DLys2,2 D- Leu3,3L- Pro4,4X5,5 ) 2, whe
