99621-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99621-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,2 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99621-97:
(7*9)+(6*9)+(5*6)+(4*2)+(3*1)+(2*9)+(1*7)=183
183 % 10 = 3
So 99621-97-3 is a valid CAS Registry Number.

Total synthesis of maesanin and analogues
Poigny, Stephane,Guyot, Michele,Samadi, Mohammad
, p. 14791 - 14802 (2007/10/03)
An efficient total synthesis of maesanin and related quinones is reported, through direct alkylation of 1,2,4,5-tetramethoxybenzene with alkylbromides, followed by oxidation with ceric ammonium nitrate (CAN) which provokes formation of the quinone and dep
