522648-82-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 522648-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,2,6,4 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 522648-82:
(8*5)+(7*2)+(6*2)+(5*6)+(4*4)+(3*8)+(2*8)+(1*2)=154
154 % 10 = 4
So 522648-82-4 is a valid CAS Registry Number.

, p. 1177 - 1187 (2007/10/03)
We report an efficient entry into substituted 3-(ω-aminoalkyl)-benzo[b]thiophenes that allows rapid generation of structural diversity. Alkylation of α,ω-dihaloketones with thiophenols followed by acid-catalysed cyclisation led to an efficient synthesis o
