Check Digit Verification of cas no

The CAS Registry Mumber 220599-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,9 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220599-51:
(8*2)+(7*2)+(6*0)+(5*5)+(4*9)+(3*9)+(2*5)+(1*1)=129
129 % 10 = 9
So 220599-51-9 is a valid CAS Registry Number.

Influence of bromoalkyloxy side chain on mesomorphic behavior in heterocyclic 7-(4-bromoalkyloxy)-3-(4′-decyloxyphenyl)-4H-1-benzopyran-4- ones

Yeap, Guan Yeow,Chan, Tze Nee,Yam, Wan Sinn,Takeuchi, Daisuke,Ito, Masato M.

, p. 947 - 950 (2012/01/11)

A new homologous series of isoflavone-based ethers, 7-(4-bromoalkyloxy)-3- (4′-decyloxyphenyl)-4H-1-benzopyran-4-ones were synthesized and characterized. The mesomorphic properties of all homologues were investigated by differential scanning calorimetry (
