504421-99-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 504421-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,4,4,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 504421-99:
(8*5)+(7*0)+(6*4)+(5*4)+(4*2)+(3*1)+(2*9)+(1*9)=122
122 % 10 = 2
So 504421-99-2 is a valid CAS Registry Number.

Chemistry of aminophenols. Part 3: First synthesis of nitrobenzo[b]furans via a coupling-cyclization approach

Dai, Wei-Min,Lai, Kwong Wah

, p. 9377 - 9380 (2007/10/03)

The first synthesis of 4-, 5-, and 6-nitrobenzo[b]furans has been achieved via the Sonogashira cross-coupling reaction of 2-iodonitrophenol acetates prepared from commercially available and inexpensive 2-aminonitrophenols. The obtained 2-alkynylnitropheno
