80693-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80693-50-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,9 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 80693-50:
(7*8)+(6*0)+(5*6)+(4*9)+(3*3)+(2*5)+(1*0)=141
141 % 10 = 1
So 80693-50-1 is a valid CAS Registry Number.

A Simple Synthesis of 5,3'-Dihydroxy-4'-methoxyflavanone
Deshpande, V. H.,Patil, A. D.
, p. 917 - 918 (2007/10/02)
The title flavanone has now been synthesized in two steps: (i) condensation of 2-acetylresorcinol and isovanillin in the presence of aq. ethanolic potassium hydroxide affords 3,2',6'-trihydroxy-4-methoxychalkone; (ii) cyclization of the resulting chalkone
