75556-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75556-15-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,5 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75556-15:
(7*7)+(6*5)+(5*5)+(4*5)+(3*6)+(2*1)+(1*5)=149
149 % 10 = 9
So 75556-15-9 is a valid CAS Registry Number.

Total Synthesis of Two Furanomycin Stereoisomers
Chen, Shin-Yih,Joullie, Madeleine M.
, p. 1769 - 1772 (2007/10/02)
D-Glucosamine hydrochloride (3), an inexpensive, commercially available reagent, has been transformed stereoselectively into two new stereoisomers of furanomycin, (αR,2S,5R)-furanomycin (2a) and its isomer with the opposite configuration at the amino acid
