219144-60-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219144-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,1,4 and 4 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219144-60:
(8*2)+(7*1)+(6*9)+(5*1)+(4*4)+(3*4)+(2*6)+(1*0)=122
122 % 10 = 2
So 219144-60-2 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
