244778-28-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244778-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,7,7 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 244778-28:
(8*2)+(7*4)+(6*4)+(5*7)+(4*7)+(3*8)+(2*2)+(1*8)=167
167 % 10 = 7
So 244778-28-7 is a valid CAS Registry Number.

Solid-phase synthesis of oligourea peptidomimetics
Boeijen, Astrid,Liskamp, Rob M. J.
, p. 2127 - 2135 (2007/10/03)
A procedure for the solid-phase synthesis of oligourea peptidomimetics starting from Boc-protected monomers is described. The compounds are prepared on Tentagel resin and can be obtained selectively rather as the C-terminal free acids with UV irradiation
