Check Digit Verification of cas no

The CAS Registry Mumber 1304473-82-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,4,7 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1304473-82:
(9*1)+(8*3)+(7*0)+(6*4)+(5*4)+(4*7)+(3*3)+(2*8)+(1*2)=132
132 % 10 = 2
So 1304473-82-2 is a valid CAS Registry Number.

Novel and efficient aqueous phase synthesis of N-substituted azepines via tandem Michael addition and cyclization in the presence of β-cyclodextrin

Ramesh,Murthy, S. Narayana,Nageswar

, p. 2362 - 2366 (2011)

N-substituted azepines were synthesized for the first time in water under neutral conditions by the reaction of aromatic amines, dimethyl/diethyl acetylene dicarboxylate, 2,5-dimethoxytetrahydrofuran mediated by β-cyclodextrin in high yields. β-Cyclodextrin can be recovered and reused with just a small loss of catalytic activity.
