113997-25-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113997-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,9,9 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 113997-25:
(8*1)+(7*1)+(6*3)+(5*9)+(4*9)+(3*7)+(2*2)+(1*5)=144
144 % 10 = 4
So 113997-25-4 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
