331230-41-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 331230-41-2 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 331230-41:
(8*3)+(7*3)+(6*1)+(5*2)+(4*3)+(3*0)+(2*4)+(1*1)=82
82 % 10 = 2
So 331230-41-2 is a valid CAS Registry Number.

Selective monoprotection of 1,4,7,10-tetraazacyclododecane via direct reaction with 4-nitrophenyl active esters

Skwierawska, Anna M.

, p. 6308 - 6310 (2008)

A simple, one-pot preparation of monoprotected 1,4,7,10-tetraazacyclododecanes via an efficient acylation reaction with 4-nitrophenyl active esters has been developed.

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
