Check Digit Verification of cas no

The CAS Registry Mumber 181289-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,8 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 181289-06:
(8*1)+(7*8)+(6*1)+(5*2)+(4*8)+(3*9)+(2*0)+(1*6)=145
145 % 10 = 5
So 181289-06-5 is a valid CAS Registry Number.

Utility of azetidinium methanesulfonates for radiosynthesis of 3-[ 18F]fluoropropyl amines

Kiesewetter, Dale O.,Eckelman, William C.

, p. 953 - 969 (2007/10/03)

3-Methanesulfonyloxypropyl tertiary amines were observed to cyclize to form azetidinium methanesulfonate moieties. Heat-induced cyclization of 3-methanesulfonyloxypropyl amines was utilized for preparation of azetidinium methanesulfonates. The azetidinium methanesulfonates were found to incorporate radioactive [18F]fluoride (decay-corrected yields > 60%) efficiently, resulting in an efficient synthesis of 3-[18F] fluoropropyl tertiary amines.
