153647-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153647-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,6,4 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 153647-56:
(8*1)+(7*5)+(6*3)+(5*6)+(4*4)+(3*7)+(2*5)+(1*6)=144
144 % 10 = 4
So 153647-56-4 is a valid CAS Registry Number.

Peptide Bond Formation via an Intramolecular Rearrangement
Wijkmans, Jac C. H. M.,Boom, Jacques H. van,Bloemhoff, Wim
, p. 7123 - 7126 (2007/10/02)
Intramolecular peptide synthesis could be achieved using tetrahydrophthalazine (1) as template.Peptide bond formation proceeded via the N-acyl-N'-α-aminoacylhydrazine-rearrangement.The feasibility of the approach is illustrated by the synthesis of the pro
