Uses
5-(Acetyloxy)-3-[4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]-7-hydroxy-4H-1-benzopyran-4-one is an protected intermediate of Genistein (G350000).
Check Digit Verification of cas no
The CAS Registry Mumber 656229-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,2,2 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 656229-80:
(8*6)+(7*5)+(6*6)+(5*2)+(4*2)+(3*9)+(2*8)+(1*0)=180
180 % 10 = 0
So 656229-80-0 is a valid CAS Registry Number.
