Check Digit Verification of cas no

The CAS Registry Mumber 869963-19-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,9,9,6 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 869963-19:
(8*8)+(7*6)+(6*9)+(5*9)+(4*6)+(3*3)+(2*1)+(1*9)=249
249 % 10 = 9
So 869963-19-9 is a valid CAS Registry Number.

New building blocks based on truxene cores: Synthesis of functionalized syn-tri- and -hexasubstituted derivatives

Gonzalez-Cantalapiedra, Esther,Ruiz, Marta,Gomez-Lor, Berta,Alonso, Beatriz,Garcia-Cuadrado, Domingo,Cardenas, Diego J.,Echavarren, Antonio M.

, p. 4127 - 4140 (2005)

Hexasubstituted truxenes are obtained in one step by alkylation of the potassium anion of truxene. Subsequent derivatization provides truxene derivatives with six carboxy, amino, or hydroxy groups at their peripheries. Alkylation of syn-5,10,15-tribenzyl derivatives with a different benzyl bromide derivative affords mixtures of anti- and syn-hexasubstituted truxenes. Truxenes with phenols or benzoquinone groups have also been synthesized by starting from truxenetrione. Wiley-VCH Verlag GmbH & Co. KGaA, 2005.
