Check Digit Verification of cas no
The CAS Registry Mumber 36155-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,1,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 36155-75:
(7*3)+(6*6)+(5*1)+(4*5)+(3*5)+(2*7)+(1*5)=116
116 % 10 = 6
So 36155-75-6 is a valid CAS Registry Number.

Synthesis of 2,3-Substituted Thienylboronic Acids and Esters
Christophersen, Claus,Begtrup, Mikael,Ebdrup, Soren,Petersen, Henning,Vedso, Per
, p. 9513 - 9516 (2007/10/03)
A noncryogenic protocol for the synthesis of 2-substituted 3-thienylboronic acids and esters as well as 3-substituted 2-thienylboronic acids and esters has been developed. Electrophiles were introduced regiospecifically in the 2-position of 2,3-dibromothiophene and in the 3-position of 2-bromo-3-iodothiophene by halogen-magnesium exchange followed by quenching with electrophiles. Palladium-catalyzed borylation of the 2,3-substituted halothiophenes with pinacolborane and P(t-Bu)3 as ligand for Pd produced 9 and 10. The borylation protocol was tolerated by a range of functional groups; however, strongly electron-withdrawing substituents decreased the stability of the thienylboronic acids and esters.
