261173-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 261173-12-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,1,7 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 261173-12:
(8*2)+(7*6)+(6*1)+(5*1)+(4*7)+(3*3)+(2*1)+(1*2)=110
110 % 10 = 0
So 261173-12-0 is a valid CAS Registry Number.

Synthesis of carbon-14 labelled NK-1 receptor antagonists GR203040 and GR205171
Cable, Karl M.,Wells, Guy N.,Sutherland, Derek R.
, p. 29 - 45 (2007/10/03)
Syntheses of carbon-14 labelled versions of NK-1 receptor antagonists GR203040 and GR205171 are described. The carbon-14 atoms were introduced by palladium (0) catalysed cyanation of iodoaromatic substrates.
