152509-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152509-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,5,0 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 152509-80:
(8*1)+(7*5)+(6*2)+(5*5)+(4*0)+(3*9)+(2*8)+(1*0)=123
123 % 10 = 3
So 152509-80-3 is a valid CAS Registry Number.

HYDROBROMINATION OF N-ARYLSULFONYL-1,4-BENZO(NAPHTHO)QUINONE MONO- AND DIIMINES
Avdeenko, A. P.,Velichko, N. V.
, p. 986 - 991 (2007/10/02)
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
