Check Digit Verification of cas no

The CAS Registry Mumber 174355-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,3,5 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174355-83:
(8*1)+(7*7)+(6*4)+(5*3)+(4*5)+(3*5)+(2*8)+(1*3)=150
150 % 10 = 0
So 174355-83-0 is a valid CAS Registry Number.

Synthesis and evaluation of thioether-based tris-melamines as components of self-assembled aggregates based on the CA·M lattice

Li, Xinhua,Chin, Donovan N.,Whitesides, George M.

, p. 1779 - 1786 (2007/10/03)

Two new tris-melamine derivatives, triazine-thio-M3 (5) (C3N3-2,4,6-[SCH2C6H 4-3-N(CH2C6H4-4-C(CH 3)3)COC6N3-2-NHC3N 3(NH2)(NHCH2CH2C(CH 3)3)-5-Br]3) and benzene-thio-M3 (6) (C6H3-1,3,5-[SCH2C6H 4-3-N(CH2C6H4-4-C(CH 3)3)(COC6H3-2-NHC3N 3(NH2)(NHCH2CH2C(CH 3)3):5-Br]3), were synthesized by reactions of 2,4,6-trithiocyanuric acid and 1,3,5-trimercaptobenzene with a bromobenzyl melamine derivative 19 (BrCH2C6H4-3-N(CH2C 6H4-4-C(CH3)3)COC6H 3-2-NHC3N3(NH2)(NHCH 2-CH2C(CH3)3)-5-Br). These two compounds formed stable and structurally well-defined 1 + 3 supramolecular aggregates with neohexyl isocyanurate (R′CA) (9) as shown by NMR spectroscopy and gel permeation chromatography. 1H NMR competition experiments indicated that the stability of triazine-thio-M3-(R′CA)3 (1) was similar to that of benzene-thio-M3-(R′CA)3 (2). The order of stabilities of tris-melamine-based 1 + 3 complexes was hubM3·(R′CA)3 (3) > triazine-thio-M3·(R'CA)3 (1) ~ benzene-thio-M3·(R′CA)3 (2) > flexM3·(R′CA)3 (4). Computational simulations were also carried out on triazine-thio-M3·(R′CA)3 and hubM3·(R′CA)3 fully solvated in CHCl3. Values of DP (the deviation from planarity of the cyanuric acid and melamine rosette) obtained from these simulations correlated correctly with the observed stabilities and suggested a structural reason why triazinethio-M3-(R′CA)3 was less stable than hubM3·(RCA)3.
