Check Digit Verification of cas no
The CAS Registry Mumber 20881-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,8 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20881-03:
(7*2)+(6*0)+(5*8)+(4*8)+(3*1)+(2*0)+(1*3)=92
92 % 10 = 2
So 20881-03-2 is a valid CAS Registry Number.

Diastereoselective Michael-Claisen cyclizations of γ-oxa-α,β-unsaturated ketones en route to 5-oxatetracyclines
Liu, Fan,Wright, Peter M.,Myers, Andrew G.
, p. 206 - 209 (2017)
5-Oxatetracyclines were synthesized from D-arabinose using sequential Michael-Claisen cyclization reactions via a 5-oxa-AB enone substrate. The 5-oxatetracyclines were found to have poor stability in aqueous buffer (pH 7.4, 37°C) and showed little to no inhibition of bacterial growth (S. aureus, E. coli).
