87232-86-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87232-86-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,3 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87232-86:
(7*8)+(6*7)+(5*2)+(4*3)+(3*2)+(2*8)+(1*6)=148
148 % 10 = 8
So 87232-86-8 is a valid CAS Registry Number.

A New Synthesis of 3,6-Dimethoxy-8,8-dimethylpyranoflavone
Pathak, V. P.,Khanna, R. N.
, p. 487 (2007/10/02)
The title pyranoflavone (I) has been synthesised starting from 4-benzyloxy-2,5-dihydroxy-ω-methoxyacetophenone (VI).VI on condensation with benzoic anhydride and sodium benzoate gives 7-benzyloxy-6-hydroxy-3-methoxyflavone (III).The latter on methylation
