Check Digit Verification of cas no

The CAS Registry Mumber 129885-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,8 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129885-57:
(8*1)+(7*2)+(6*9)+(5*8)+(4*8)+(3*5)+(2*5)+(1*7)=180
180 % 10 = 0
So 129885-57-0 is a valid CAS Registry Number.

N-hydroxypyridine-2-thione carbamates. V. Syntheses of alkaloid skeletons by aminium cation radical cyclizations

Newcomb, Martin,Marquardt, Donald J.,Deeb, Thomas M.

, p. 2329 - 2344 (2007/10/02)

The title radical precursors (PTOC carbamates) were employed as sources of a variety of 5,6-unsaturated aminium cation radicals. 5-Exo radical cyclization followed by trapping by t-BuSH or the PTOC carbamate gave a variety of aklaloid skeletons, typically in good to excellent yields, including pyrrolidines, perhydroindoles, pyrrolizidines, tropanes, 9-azabicyclo[4.2.1]nonanes, 6-azabicyclo [3.2.1]octanes. 6-Exo and 7-endo cyclizations competed in a 6,7-unsaturated system.
