83893-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83893-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,9 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83893-50:
(7*8)+(6*3)+(5*8)+(4*9)+(3*3)+(2*5)+(1*0)=169
169 % 10 = 9
So 83893-50-9 is a valid CAS Registry Number.

Synthesis of Dihydrobenzofuran Derivatives from Substituted p-Benzoquinones
Kozuka, Tadashi
, p. 2415 - 2423 (2007/10/02)
A series of p-benzoquinones having an ester functional group in the α position of alkyl side chains was prepared.Irradiation of these quinones, except for methyl 3-methyl-2-(4-methyl-3,6-dioxo-1,4-cyclohexadienyl)-butyrate (3e), rapidly gave methyl 3-subs
