127745-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127745-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127745-89:
(8*1)+(7*2)+(6*7)+(5*7)+(4*4)+(3*5)+(2*8)+(1*9)=155
155 % 10 = 5
So 127745-89-5 is a valid CAS Registry Number.

STRUCTURE OF PRODUCTS FROM THE REACTION OF N-ARYLSULFONYL-p-QUINONE IMINES WITH NAPHTHOLS
Avdeenko, A. P.
, p. 2141 - 2146 (2007/10/02)
Evidence was obtained for the addition of 2-naphthols to N-arylsulfonyl-p-benzo(naphtho)quinone imines at position 1 and of 1-naphthols at position 2 with the formation of 2-hydroxyaryl-4-arylsulfonylaminophenols (or the corresponding 1-naphthols). 5-Phen
