321577-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 321577-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,5,7 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 321577-35:
(8*3)+(7*2)+(6*1)+(5*5)+(4*7)+(3*7)+(2*3)+(1*5)=129
129 % 10 = 9
So 321577-35-9 is a valid CAS Registry Number.

HYDROBROMINATION OF N-ARYLSULFONYL-1,4-BENZO(NAPHTHO)QUINONE MONO- AND DIIMINES

The hydrobromination of N-arylsulfonyl-1,4-benzo(naphtho)quinone monoimines led to 2-bromo-4-arenesulfonamidophenols (or the corresponding 1-naphthols) and 2,6-dibromo-4-arenesulfonamidophenols.Their oxidation gave N-arylsulfonyl-2-bromo-1,4-benzo(naphtho
