Check Digit Verification of cas no

The CAS Registry Mumber 761448-37-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,1,4,4 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 761448-37:
(8*7)+(7*6)+(6*1)+(5*4)+(4*4)+(3*8)+(2*3)+(1*7)=177
177 % 10 = 7
So 761448-37-7 is a valid CAS Registry Number.

Chromophoric Macrocycles from the Oxidation of Bis(aminofurazanylic) Ethers of 1,2-Diols

Sheremetev, Aleksei B.,Shatunova, Elena V.,Averkiev, Boris B.,Dmitriev, Dmitrii E.,Petukhov, Viktor A.,Antipin, Mikhail Yu.

, p. 131 - 145 (2004)

A series of chromophoric azofurazan-containing macrocycles 6a-c and 7a-d were synthesized from bis(aminofurazanylic) ethers of 1,2-diols 4a-d by dibromoisocyanurate oxidation. The macrocycle closure is a result of N=N bond formation. An ion-binding ability of these compounds was tested. The macrocycles were characterized by NMR, MS, IR, and UV spectroscopy. The X-ray crystal structures of the macrocycles 6a, 7c, and linear counterpart 12 are reported.
