78050-54-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78050-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,5 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78050-54:
(7*7)+(6*8)+(5*0)+(4*5)+(3*0)+(2*5)+(1*4)=131
131 % 10 = 1
So 78050-54-1 is a valid CAS Registry Number.

, p. 115 - 118 (2007/10/02)
The boundaries of application of the one-step synthesis of flavylium salts on the basis of bromoresacetophenone were extended, and the conditions for heterocyclization of 2', 4'-dihydroxy-5'-bromochalcones to 4-ethoxyflavylium salts were studied simultane
