Check Digit Verification of cas no
The CAS Registry Mumber 1256355-38-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,3,5 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1256355-38:
(9*1)+(8*2)+(7*5)+(6*6)+(5*3)+(4*5)+(3*5)+(2*3)+(1*8)=160
160 % 10 = 0
So 1256355-38-0 is a valid CAS Registry Number.

Preparation of brominated 2-alkoxythiophenes via oxidation and etherification of 2-thienyltrifluoroborate salts

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.
