Check Digit Verification of cas no

The CAS Registry Mumber 177593-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,5,9 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 177593-50:
(8*1)+(7*7)+(6*7)+(5*5)+(4*9)+(3*3)+(2*5)+(1*0)=179
179 % 10 = 9
So 177593-50-9 is a valid CAS Registry Number.

Tris(triorganostannyltetrazoles): Synthesis and supramolecular structures

Hill, Michael,Mahon, Mary F.,Molloy, Kieran C.

, p. 1857 - 1865 (1996)

Six trifunctional triorganotin tetrazoles, (R3SnN4CCH2CH2)3C(NO 2) and 1,3,5-(R3SnN4C)3C6H3(R = Me, Et or Bu), have been synthesised by a cycloaddition route from SnR3(N3) and either (NCCH2CH2)3C(NO2) or 1,3,5-(NC)3C6H3 as dipblarophile. The compounds have been characterised by 1H, 13C, 119Sn NMR and 119Moessbauer spectroscopies, while the crystal structures of the tributyltin examples of each series reveal they adopt layered supramolecular arrays.
