77693-08-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77693-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,9 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77693-08:
(7*7)+(6*7)+(5*6)+(4*9)+(3*3)+(2*0)+(1*8)=174
174 % 10 = 4
So 77693-08-4 is a valid CAS Registry Number.

A Convenient Synthesis of Pinnatin
Ahluwalia, V. K.,Prakash, Chandra,Mehta, Kamal Deep,Singh, R. P.
, p. 1081 - 1082 (2007/10/02)
The new synthesis of pinnatin (I) involves conversion of 4-allyloxy-2-hydroxy-3-iodo-6-methoxyacetophenone (V) into 7-allyloxy-8-iodo-5-methoxyflavone (III) by benzoylation, Baker-Venkataraman migration and cyclisation of the formed dibenzoylmethane (VII)
