73331-65-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73331-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,3 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73331-65:
(7*7)+(6*3)+(5*3)+(4*3)+(3*1)+(2*6)+(1*5)=114
114 % 10 = 4
So 73331-65-4 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
