Check Digit Verification of cas no

The CAS Registry Mumber 91165-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,6 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91165-52:
(7*9)+(6*1)+(5*1)+(4*6)+(3*5)+(2*5)+(1*2)=125
125 % 10 = 5
So 91165-52-5 is a valid CAS Registry Number.

Syntheses and Spectroscopic Studies of 1,8-Bistriazolylnaphthalenes

Honda, Koichi,Nakanishi, Hiroshi,Nagawa, Yoshinobu,Yabe, Akira

, p. 450 - 451 (2007/10/02)

The first 1,8-diheterocyclic naphthalenes, the 1,8-bis(1'H-1',2',3'-triazolyl)naphthalenes (1a - i), have been synthesized by 1,3-dipolar cycloadditions of 1,8-diazidonaphthalene to acetylenic esters or enolates of acetoacetic esters, and have strained structures as revealed by comparison of their spectral properties with those of the corresponding 1-(1'H-1',2',3'-triazolyl)naphthalenes.
