118092-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118092-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,9 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118092-40:
(8*1)+(7*1)+(6*8)+(5*0)+(4*9)+(3*2)+(2*4)+(1*0)=113
113 % 10 = 3
So 118092-40-3 is a valid CAS Registry Number.

, p. 555 - 558 (2007/10/02)
New flavones (4b-f/6) with formyl functions in the 3-, 4'-, 6- and 4',6-positions are synthesized from bromomethyl or dibromomethyl flavone derivatives (3a-e) with methylflavones (2a-e) as starting compounds.The formyl flavones are suitable synthetic tool
