1290130-76-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1290130-76-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,1,3 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1290130-76:
(9*1)+(8*2)+(7*9)+(6*0)+(5*1)+(4*3)+(3*0)+(2*7)+(1*6)=125
125 % 10 = 5
So 1290130-76-5 is a valid CAS Registry Number.

D-Glucose based syntheses of β-hydroxy derivatives of l-glutamic acid, l-glutamine, l-proline and a dihydroxy pyrrolidine alkaloid

Kumar, K. S. Ajish,Chattopadhyay, Subrata

, p. 19455 - 19464 (2015)

The β-hydroxy derivatives of l-glutamic acid, l-glutamine and l-proline, useful for peptide/protein studies, were synthesized starting from d-glucose. The C2 carbon in d-glucose provided the carboxylic acid functionality, while the amino and β-hydroxy groups of the amino acids were amenable from the C3 and C4 hydroxy groups of the sugar, respectively. The key intermediate with appropriate carbon framework of the target molecules was constructed by homologation of a suitable azido-d-glucofuranose derivative using the Arndt-Eistert reaction.
