Check Digit Verification of cas no
The CAS Registry Mumber 204316-32-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,3,1 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 204316-32:
(8*2)+(7*0)+(6*4)+(5*3)+(4*1)+(3*6)+(2*3)+(1*2)=85
85 % 10 = 5
So 204316-32-5 is a valid CAS Registry Number.

Practical and efficient synthesis of orthogonally protected α-2,3-diaminopropionic acid (2,3-Dap), 2,4-diaminobutanoic acid (2,4-Dab), and their N-methylated derivatives

The synthesis of orthogonally protected Fmoc-Dap/Dab (Boc/Z/Alloc)-OH starting from Fmoc-Asp/Glu has been described. The salient features of our synthetic strategy involved formation of Fmoc-Asp/Glu-5-oxazolidinone acids, conversion of acid function to acyl azides, Curtius rearrangement, and hydrolysis of the oxazolidinone group.
