Check Digit Verification of cas no

The CAS Registry Mumber 919106-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,9,1,0 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 919106-05:
(8*9)+(7*1)+(6*9)+(5*1)+(4*0)+(3*6)+(2*0)+(1*5)=161
161 % 10 = 1
So 919106-05-1 is a valid CAS Registry Number.

Synthesis of tetraazacalix[2]arene[2]-triazines: Tuning the cavity by the substituents on the bridging nitrogen atoms

Wang, Qi-Qiang,Wang, De-Xian,Ma, Hong-Wei,Wang, Mei-Xiang

, p. 5967 - 5970 (2007/10/03)

(Chemical Equation Presented) A number of tetraazacalix[2]arene[2]triazines bearing different substituents on the bridging nitrogen atoms were synthesized efficiently using a fragment coupling strategy. The N-arylation of the parent azacalix[2]arene[2]tri
