29169-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29169-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,1,6 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29169-19:
(7*2)+(6*9)+(5*1)+(4*6)+(3*9)+(2*1)+(1*9)=135
135 % 10 = 5
So 29169-19-5 is a valid CAS Registry Number.

, p. 395 - 399 (1997)
To synthesize no-carrier-added potassium [18F]fluoroacetate, O-mesyl glycolate ethyl ester and O-tosyl glycolate ethyl ester were synthesized as precursors. These precursors were radiolabeled by reacting with dried tetrabutylammonium [18/
