The CAS Registry Mumber 142182-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,8 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142182-54:
(8*1)+(7*4)+(6*2)+(5*1)+(4*8)+(3*2)+(2*5)+(1*4)=105
105 % 10 = 5
So 142182-54-5 is a valid CAS Registry Number.

Synthesis of naturally occurring rubilactone, mollugin, and dihydromollugin of Rubia cordifolia

Ho, Li-Kang,Yu, Hsi-Jung,Ho, Chen-Ta,Don, Ming-Jaw

, p. 77 - 79 (2001)

Rubilactone (1), dihydromollugin (2), and mollugin (3) are naturally occurring products found in Rubia cordifolia, which is a famous Chinese herb with antitumor, viral inhibition and other activities. Synthetic studies were carried out in these naphthoic acid esters starting from 1,4-dihydroxy-2-naphthoic acid. In this study, we finished the synthesis of rubilactone which has not been reported before and also synthesized dihydromollugin and mollugin with better yields with different approaches compared to those previously reported in the literature.
