Check Digit Verification of cas no

The CAS Registry Mumber 855267-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,2,6 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 855267-34:
(8*8)+(7*5)+(6*5)+(5*2)+(4*6)+(3*7)+(2*3)+(1*4)=194
194 % 10 = 4
So 855267-34-4 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.
