89726-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89726-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,2 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89726-56:
(7*8)+(6*9)+(5*7)+(4*2)+(3*6)+(2*5)+(1*6)=187
187 % 10 = 7
So 89726-56-7 is a valid CAS Registry Number.

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
