Check Digit Verification of cas no
The CAS Registry Mumber 231300-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,3,0 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 231300-44:
(8*2)+(7*3)+(6*1)+(5*3)+(4*0)+(3*0)+(2*4)+(1*4)=70
70 % 10 = 0
So 231300-44-0 is a valid CAS Registry Number.

Dihydrothienopsoralens: New furocoumarins as potential photoreacting agents
Zoubir,Refouvelet,Aubin,Humbert,Xicluna
, p. 509 - 513 (2007/10/03)
A series of new dihydrothienopsoralen derivatives were synthesized from 6-hydroxybenzo[b]furan in four steps in good yield. These compounds were prepared as potential photosensitizing and chemotherapeutic agents for psoriasis. The spectroscopy study in al
