Check Digit Verification of cas no

The CAS Registry Mumber 1025975-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,9,7 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1025975-08:
(9*1)+(8*0)+(7*2)+(6*5)+(5*9)+(4*7)+(3*5)+(2*0)+(1*8)=149
149 % 10 = 9
So 1025975-08-9 is a valid CAS Registry Number.

Temperature dependent inversion of enantiomer selectivity in the complexation of optically active azophenolic crown ethers containing alkyl substituents as chiral barriers with chiral amines

Hirose, Keiji,Fuji, Junichi,Kamada, Kimiko,Tobe, Yoshito,Naemura, Koichiro

, p. 1649 - 1657 (2007/10/03)

Azophenolic crown ethers (S,S)-1, (R,R)-2 and (S,S)-3 have been prepared in enantiomerically pure forms by using (S)-1-(1′-adamantyl)ethane-1,2-diol, (R)-3,3-dimethylbutane-1,2-diol and (S)-propane-1,2-diol, respectively, as chiral subunits, and the assoc
