Check Digit Verification of cas no

The CAS Registry Mumber 1414607-48-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,4,6,0 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1414607-48:
(9*1)+(8*4)+(7*1)+(6*4)+(5*6)+(4*0)+(3*7)+(2*4)+(1*8)=139
139 % 10 = 9
So 1414607-48-9 is a valid CAS Registry Number.

Synthesis of protected 4-amino- and 4-azido-3-hydroxy-l-prolines from d-glucose

Kasture, Vijay M.,Kalamkar, Navnath B.,Dhavale, Dilip D.

, p. 2735 - 2738 (2012/11/07)

Differentially protected 4-azido- or 4-amino-3-hydroxy-l-prolines were synthesized in good overall yields (21-31%) from d-glucose. The synthetic strategy involved conversion of d-glucose into 3-[(benzyloxycarbonyl)amino]-3- deoxy-1,2-O-isopropylidene-α-d-glucofuranose, which was subjected to mesylation of the 5- and 6-hydroxy groups and subsequent intramolecular S N2 displacement of the 6-O-mesyl group by the 3-(benzyloxycarbonyl) amino group to give a pyrrolidine ring. The resulting intermediate underwent intermolecular SN2 displacement of the 5-O-mesyl group with sodium azide, hydrolysis of 1,2-acetonide group, treatment with sodium periodate, and Pinnick oxidation to give the required compounds.
