Check Digit Verification of cas no
The CAS Registry Mumber 22059-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22059-22:
(7*2)+(6*2)+(5*0)+(4*5)+(3*9)+(2*2)+(1*2)=79
79 % 10 = 9
So 22059-22-9 is a valid CAS Registry Number.

, p. 7316 - 7321 (2007/10/03)
Various 3-substituted chiral 1,2,4-oxadiazole-containing Fmoc-β 3- and α-amino acids were synthesized from FmoC-(L or D)-Asp(OtBu)-OH and Fmoc-L-Asp-OtBu, respectively, in three steps (i.e., condensation of an aspartyl derivative with different
