Check Digit Verification of cas no

The CAS Registry Mumber 133871-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,7 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133871-01:
(8*1)+(7*3)+(6*3)+(5*8)+(4*7)+(3*1)+(2*0)+(1*1)=119
119 % 10 = 9
So 133871-01-9 is a valid CAS Registry Number.

Photochemistry of Tetrabenzotetraazacyclododecine in 2-Propanol

Tauer, Erich,Grellmann, Karl-Heinz,Heinrich, Angelika

, p. 2053 - 2055 (2007/10/02)

The photochemical properties of the tetraazacyclododecine 1 were investigated.The trans,trans isomer 1tt can be photoisomerized yielding the stable cis,cis isomer 1cc.The isomerization requires two photons and proceeds via the unstable trans,cis isomer 1tc.In nitrogen-purged 2-propanol as solvent 1 yields five stable photoproducts as a result of a number of consecutive photoreduction reactions.Our attempts to convert 1 by light into the tetraazetidine 4 were not successful. Key Words: cis-Azo compounds / Photoreduction / Tetrabenzotetraazacyclododecine
