Check Digit Verification of cas no
The CAS Registry Mumber 1239370-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,3,7 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1239370-98:
(9*1)+(8*2)+(7*3)+(6*9)+(5*3)+(4*7)+(3*0)+(2*9)+(1*8)=169
169 % 10 = 9
So 1239370-98-9 is a valid CAS Registry Number.

Preparation of brominated 2-alkoxythiophenes via oxidation and etherification of 2-thienyltrifluoroborate salts
Tietz, Jonathan I.,Seed, Alexander J.,Sampson, Paul
supporting information, p. 5058 - 5061 (2013/01/15)
The synthesis of ring brominated long-chain 2-alkoxythiophenes is reported, involving mild (Oxone) oxidation of readily prepared 2-thienyltrifluoroborate salts followed by Mitsunobu etherification. Both procedures are operationally straightforward and use inexpensive reagents. Using this approach, several novel mono- and dibrominated octyloxythiophenes with previously elusive substitution patterns were prepared. One such compound was elaborated to a novel 5-alkoxythieno[3,2-b]thiophene-2-carboxylate ester, marking the first synthetic entry into this family of compounds.
