124360-79-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124360-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,6 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124360-79:
(8*1)+(7*2)+(6*4)+(5*3)+(4*6)+(3*0)+(2*7)+(1*9)=108
108 % 10 = 8
So 124360-79-8 is a valid CAS Registry Number.

Synthesis of Pyranoisoflavones from Pyronochalcones: Synthesis of Elongatin and Its Angular Isomer

Tsukayama, Masao,Kawamura, Yasuhiko,Tamaki, Hiroto,Kubo, Tomoya,Horie, Tokunaru

, p. 826 - 832 (2007/10/02)

Elongatin (4',5-dihydroxy-2',5'-dimethoxy-2'',2''-dimethylpyranoisoflavone) was synthesized by an oxidative rearrangement of the corresponding pyronochalcone with thallium(III) nitrate and a regioselective reduction of 7-(4-benzoyloxy-2,5-dimethoxyphenyl)-2,3-dihydro-2,2-dimethyl-5-tosyloxy-4H,6H-benzodipyran-4,6-dione with sodium borohydride-palladium chloride, followed by dehydration of the resultant alcohol and hydrolysis.Its angular isomer (4',5-dihydroxy-2',5'-dimethoxy-2'',2''-dimethylpyranoisoflavone) was also synthesized from the corresponding pyronochalcone in a similar manner.
