1152169-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1152169-21-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,1,6 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1152169-21:
(9*1)+(8*1)+(7*5)+(6*2)+(5*1)+(4*6)+(3*9)+(2*2)+(1*1)=125
125 % 10 = 5
So 1152169-21-5 is a valid CAS Registry Number.

Carbon-sulfur bond cleavage of methyl-substituted thiophenes with iridium(III)
Grochowski, Matthew R.,Brennessel, William W.,Jones, William D.
, p. 2661 - 2667 (2009)
Reaction of [Cp*IrHCl]2 (Cp* = η5- C5Me5) with 2-methylthiophene and 2,5-dimethylthiophene at 120 °C in the presence of H2 results in the cleavage of the thiophene carbon-sulfur bond(s). In both cases
