Check Digit Verification of cas no

The CAS Registry Mumber 1290140-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,1,4 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1290140-63:
(9*1)+(8*2)+(7*9)+(6*0)+(5*1)+(4*4)+(3*0)+(2*6)+(1*3)=124
124 % 10 = 4
So 1290140-63-4 is a valid CAS Registry Number.

Synthesis of fluorogenic arylureas and amides and their interaction with amines: A competition between turn-on fluorescence and organic radicals on theway to a smart label for fish freshness

Cuevas, José V.,Díaz de Gre?u, Borja,García-Calvo, José,García-Tojal, Javier,Hernando-Mu?oz, Carla,Rojo, María-Josefa,Salgado, Mateo M.,Torroba, Tomás

, (2021)

We describe the synthesis of fluorogenic arylureas and amides and their interaction with primary or secondary amines under air and light in organic-aqueous mixtures to give rise to a new class of persistent organic radicals, described on the basis of thei

A fluorescent molecular ruler as a selective probe for ω-aminoacids

Moreno, Daniel,Cuevas, Jose V.,Garcia-Herbosa, Gabriel,Torroba, Tomas

, p. 3183 - 3185 (2011/06/10)

A fluorescent probe for ω-aminoacids behaves as a molecular ruler, changing the yellow fluorescent emission into blue as a function of the distance between the terminal ammonium and the carboxylate groups, permitting the quantitative detection of ω-aminoa
