Check Digit Verification of cas no
The CAS Registry Mumber 155307-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155307-81:
(8*1)+(7*5)+(6*5)+(5*3)+(4*0)+(3*7)+(2*8)+(1*1)=126

The novel 7-fluoro-4-chromone-3-sulfur compounds 5-12 were synthesized from the sulfinic acid 4, which can be obtained from the enaminone 3 and thionyl chloride. Especially the Flosequinane-like sulfoxide 12 was prepared and the vasodilating activity was
