58554-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58554-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,5,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58554-83:
(7*5)+(6*8)+(5*5)+(4*5)+(3*4)+(2*8)+(1*3)=159
159 % 10 = 9
So 58554-83-9 is a valid CAS Registry Number.

3-Acetylbiphenyl-4-ol and -2-ol were condensed with substituted benzaldehydes to give respectively 5 prime - and 3 prime -phenyl-substituted chalcones which were cyclized to afford 6- and 8-phenylflavanones. The chalcones also gave the corresponding 6- an
