Check Digit Verification of cas no

The CAS Registry Mumber 1093936-42-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,9,3 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1093936-42:
(9*1)+(8*0)+(7*9)+(6*3)+(5*9)+(4*3)+(3*6)+(2*4)+(1*2)=175
175 % 10 = 5
So 1093936-42-5 is a valid CAS Registry Number.

Synthesis and self-assembly of dibenzo[jk,mn]naphtho[2,1,8-fgh]thebenidinium derivates

Wu, Dongqing,Feng, Xinliang,Takase, Masayoshi,Haberecht, Monika C.,Müllen, Klaus

, p. 11379 - 11386 (2008)

A novel synthetic method toward nitrogen containing positively charged dibenzo[jk,mn]naphtho[2,1,8-fgh]thebenidinium (DBNT, 1) salts was developed. In this method, the undehydrogenated precursor of DBNT, 14-phenyl-14-dibenzo[a,j]acridinium salt (6), was produced directly from the reaction between 14-phenyl-14-dibenzo[a,j]xanthenylium (2) and amine/aniline in reasonable yield. Various DBNT salts with different alkyl and alkylphenyl chains were synthesized in this two-step method. The self-assembly behavior of two alkylated DBNT salts, 1c and 1f, was studied in this work. Due to the different substituents and counterions, compound 1c formed nanoscale wirelike fibers, and helical aggregates were obtained from 1f, in their methanolic solutions.
