Check Digit Verification of cas no

The CAS Registry Mumber 83326-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,2 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83326-04:
(7*8)+(6*3)+(5*3)+(4*2)+(3*6)+(2*0)+(1*4)=119
119 % 10 = 9
So 83326-04-9 is a valid CAS Registry Number.

Conformational Behaviour of Medium-sized Rings. Part 15. 1,9,17-Triazametacyclophane-2,10,18-trione Derivatives

Elhadi, Farouk Eltayeb,Ollis, W. David,Stoddart, J. Fraser

, p. 1727 - 1732 (2007/10/02)

The stepwise synthesis of 1,9-dimethyl-1,9,17-triazametacyclophane-2,10,18-trione (1) from methyl m-aminobenzoate and m-nitrobenzoyl chloride is reported.The temperature dependences (i) of the 1H-decoupled 13C n.m.r. spectrum of the 1,9,17-trimethyl derivative (2) and (ii) of the 1H n.m.r. spectrum of the 1,9-dimethyl-17-benzyl derivative (3) are interpreted in terms of equilibration between diastereoisomeric crown and saddle conformations in solution.The 1,9-dimethyl derivative (1) is believed to exist predominantly in the saddle conformation in solution.
