Check Digit Verification of cas no

The CAS Registry Mumber 331230-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,2,3 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 331230-42:
(8*3)+(7*3)+(6*1)+(5*2)+(4*3)+(3*0)+(2*4)+(1*2)=83
83 % 10 = 3
So 331230-42-3 is a valid CAS Registry Number.

Detection of NAD(P)H-dependent enzyme activity with dynamic luminescence quenching of terbium complexes

Ito, Hiroki,Terai, Takuya,Hanaoka, Kenjiro,Ueno, Tasuku,Komatsu, Toru,Nagano, Tetsuo,Urano, Yasuteru

supporting information, p. 8319 - 8322 (2015/05/13)

We discovered that positively charged terbium complexes bearing 1,4,7,10-tetraazacyclododecane functionalized with amide ligands are highly sensitive to dynamic luminescence quenching by NAD(P)H. We exploited this phenomenon to establish a general time-re

Synthesis, relaxometric and photophysical properties of a new pH-responsive MRI contrast agent: The effect of other ligating groups on dissociation of a p-nitrophenolic pendant arm

Woods, Mark,Kiefer, Garry E.,Bott, Simon,Castillo-Muzquiz, Aminta,Eshelbrenner, Carrie,Michaudet, Lydie,McMillan, Kenneth,Mudigunda, Siva D. K.,Ogrin, Doug,Tircso, Gyula,Zhang, Shanrong,Zhao, Piyu,Sherry, A. Dean

, p. 9248 - 9256 (2007/10/03)

Two gadolinium(III) chelates, GdNP-DO3A (1-methlyene-(p-NitroPhenol)-1,4,7, 10-tetraazacycloDOdecane-4,7,10-triAcetate) and GdNP-DO3AM (1-methlyene(p- NitroPhenol)-1,4,7,10-tetraazacycloDOdecane-4,7,10-triacetAMide), containing a single nitrophenolic pendant arm plus either three acetate or three amide pendant arms were synthesized and characterized. The properties of the gadolinium, terbium, and dysprosium complexes of these ligands were examined as a function of pH. The extent and mechanism of the changes in water relaxivity with pH of each gadolinium complex was found to differ substantially for the two complexes. The water relaxivity of Gd(NP-DO3A) increases from 4.1 mM -1 s-1 at pH 9 to 7.0 mM-1 s-1 at pH 5 as a result of acid-catalyzed dissociation of the nitrophenol from the lanthanide. The nitrophenol group in Gd(NP-DO3AM) does not dissociate from the metal center even at pH 5; therefore, the very modest increase in relaxivity in this complex must be ascribed to an increase in prototropic exchange rate of the bound water and/or phenolic protons.
