Check Digit Verification of cas no

The CAS Registry Mumber 1026183-20-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,1,8 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1026183-20:
(9*1)+(8*0)+(7*2)+(6*6)+(5*1)+(4*8)+(3*3)+(2*2)+(1*0)=109
109 % 10 = 9
So 1026183-20-9 is a valid CAS Registry Number.

Regioselective synthesis and estrogenicity of (±)-8-alkyl-5,7- dihydroxy-4-(4-hydroxyphenyl)-3,4-dihydrocoumarins

Roelens, Frederik,Huvaere, Kevin,Dhooge, Willem,Van Cleemput, Marjan,Comhaire, Frank,De Keukeleire, Denis

, p. 1042 - 1051 (2005)

Nine new (±)-8-alkyl-5,7-dihydroxy-4-(4-hydroxyphenyl)-3,4- dihydrocoumarins have been synthesized from 2,4,6-trimethoxybenzaldehyde via a short, efficient, and regioselective pathway, together with the unsubstituted analogue (±)-5,7-dihydroxy-4-(4-hydroxyphenyl)-3,4-dihydrocoumarin. The compounds were tested for estrogenic activity using a yeast-based estrogen screen. Weak estrogenicity was determined for seven members of the series.
