440369-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 440369-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,3,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 440369-81:
(8*4)+(7*4)+(6*0)+(5*3)+(4*6)+(3*9)+(2*8)+(1*1)=143
143 % 10 = 3
So 440369-81-3 is a valid CAS Registry Number.

The controlled assembly of modified cyclopeptide cages via scaffolded cyclooligomerisations
Pattenden, Gerald,Thompson, Toby
, p. 2459 - 2461 (2007/10/03)
Novel thiazole- and oxazole-containing modified cyclopeptide C3-symmetric cages have been synthesised utilising a trimeric linker to control the assembly and cyclooligomerisation of heterocyclic amino acids.
