Check Digit Verification of cas no

The CAS Registry Mumber 161809-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,0 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161809-92:
(8*1)+(7*6)+(6*1)+(5*8)+(4*0)+(3*9)+(2*9)+(1*2)=143
143 % 10 = 3
So 161809-92-3 is a valid CAS Registry Number.

Facile Aerial Oxidation of a Porphyrin. Part 18. N-Alkylation of the Oxidised Product Derived from Meso-tetrakis(3,5-di-t-butyl-4-hydroxyphenyl)porphyrin

Milgrom, Lionel R.,Hill, Jonathan P.,Yahioglu, Gokhan

, p. 97 - 102 (2007/10/02)

In basic solutions, the oxidised porphyrin 2 readily undergoes macrocyclic N-alkylation, with up to four bulky alkyl groups, including decyl and substituted benzyl moieties, being accomodated; an argument is presented to show that N-di-alkylation occurs on opposite nitrogen atoms, on the same side of the macrocycle.
