Check Digit Verification of cas no

The CAS Registry Mumber 1146956-25-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,6,9,5 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1146956-25:
(9*1)+(8*1)+(7*4)+(6*6)+(5*9)+(4*5)+(3*6)+(2*2)+(1*5)=173
173 % 10 = 3
So 1146956-25-3 is a valid CAS Registry Number.

Thieme Chemistry Journal awardees - Where are they now? Synthesis of p-phenylene ethynylene based macrocycles and bimacrocycle through formation of the imine bond

Wang, Liu-Gang,Li, Zhan-Ting

scheme or table, p. 384 - 389 (2009/09/06)

This paper describes the synthesis of three monomacrocycles and one bimacrocycle from two p-phenylene ethynylene frameworks. For two of the monomacrocycles, the two frameworks were linked by an amide unit and the macrocyclization involved the intramolecular formation of one imine bond. For another monomacrocycle and the bimacrocycle, the frameworks contained two and three amino or aldehyde units, respectively, and the macrocyclization involved the intermolecular formation of two and three imine bonds. Georg Thieme Verlag Stuttgart.
