137271-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137271-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137271-91:
(8*1)+(7*3)+(6*7)+(5*2)+(4*7)+(3*1)+(2*9)+(1*1)=131
131 % 10 = 1
So 137271-91-1 is a valid CAS Registry Number.

Synthetic approaches toward glidobamine, the core structure of the glidobactin antibiotics
Meng, Qingchang,Hesse, Manfred
, p. 6251 - 6264 (2007/10/02)
Peptide synthesis method was first employed to synthesize glidobamine, the core structure of the glidobactin antibiotics (2), but in a model study all attempts failed to cyclize the linear precursor 10. Then a N-N bond cleavage method was developed to con
