Check Digit Verification of cas no

The CAS Registry Mumber 128650-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,6,5 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128650-13:
(8*1)+(7*2)+(6*8)+(5*6)+(4*5)+(3*0)+(2*1)+(1*3)=125
125 % 10 = 5
So 128650-13-5 is a valid CAS Registry Number.

Synthese et proprietes biologiques photoinduites de dioxinnocoumarines lineaires

Guillaumet, Gerald,Hretani, Mohamed,Coudert, Gerard,Averbeck, Dietrich,Averbeck, Simone

, p. 45 - 51 (1990)

Synthesis and photoinduced biological properties of linear dioxinocoumarins.Several dioxinocoumarins with a substituted or unsubstituted coumarin moiety were synthesized from commercially available 6-amino-1,4-benzodioxan.Qualitative assays on the photoinduced inhibition of growth in the yeast Saccharomyces cerevisiae indicate that two dioxinocoumarins are photobiologically active. The 5H- benzopyranobenzodioxin-5-one 1d is more active than angelicin but less active than 8-MOP.The 9-methyl-7H-pyranobenzodioxin-7-one 1c is slightly less active than angelicin.
