184219-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 184219-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,2,1 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 184219-45:
(8*1)+(7*8)+(6*4)+(5*2)+(4*1)+(3*9)+(2*4)+(1*5)=142
142 % 10 = 2
So 184219-45-2 is a valid CAS Registry Number.

, p. 1318 - 1319 (2000)
2,4,6-Trimethylphenol was oxidized with oxygen in the presence of (1,4,7-tribenzyl-1,4,7-triazacyclononane)copper(II) chloride as a catalyst to produce exclusively a coupled product stilbenequinone, without the formation of oxygenated products.
