87059-79-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87059-79-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,5 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87059-79:
(7*8)+(6*7)+(5*0)+(4*5)+(3*9)+(2*7)+(1*9)=168
168 % 10 = 8
So 87059-79-8 is a valid CAS Registry Number.

EXAMINATION OF THE RING-CHAIN ISOMERISM OF 2-HYDROXY-CHROMANONES WITH 1H NMR SPECTROSCOPY
Borbely, Janos,Szabo, Vince
, p. 5813 - 5816 (2007/10/02)
In the cyclic derivatives (1) the hydroxyl group is of pseudo-axial orientation (1: α-anomer) and no equatorial form (1: β-anomer) has been detected.The ring-opened compound exits in keto-enol equilibrium (2 3) dependent of the R-substituent.
