Check Digit Verification of cas no

The CAS Registry Mumber 428453-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,8,4,5 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 428453-35:
(8*4)+(7*2)+(6*8)+(5*4)+(4*5)+(3*3)+(2*3)+(1*5)=154
154 % 10 = 4
So 428453-35-4 is a valid CAS Registry Number.

Bronsted acid-catalyzed intramolecular hydroamination of protected alkenylamines. Synthesis of pyrrolidines and piperidines.

, p. 1471 - 1474 (2007/10/03)

[reaction: see text]. The cyclization of aminoalkenes bearing an electron-withdrawing group on the nitrogen atom was catalyzed by triflic or sulfuric acid in toluene. Pyrrolidines and piperidines were formed in excellent yields. N-phenylanilides also underwent cyclization to form gamma-lactams.
