83755-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83755-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,5 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83755-89:
(7*8)+(6*3)+(5*7)+(4*5)+(3*5)+(2*8)+(1*9)=169
169 % 10 = 9
So 83755-89-9 is a valid CAS Registry Number.

The Mechanism of the Quinamine Rearrangements
Boduszek, Bogdan,Shine, Henry J.
, p. 3247 - 3252 (2007/10/02)
Acid-catalyzed rearrangement of 6-bromo-2,4-dimethyl-4(phenylamino)cyclohexa-1,4-dienone (1, a quinamine) in aqueous methanol gives, from a so-called quinamine rearrangement, 4'-amino-6-bromo-2,4-dimethyldiphenyl ether (2) and a number of byproducts.The r
