552847-85-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 552847-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,8,4 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 552847-85:
(8*5)+(7*5)+(6*2)+(5*8)+(4*4)+(3*7)+(2*8)+(1*5)=185
185 % 10 = 5
So 552847-85-5 is a valid CAS Registry Number.

Deuterated chemiluminescent 1,2-dioxetanes

-

Page/Page column 10-11, (2009/05/29)

Deuterium-based i.e. isotopic hydrogen chemiluminescent 1,2-dioxetanes derived from the photo-oxidation of new novel alkenes which are synthesized by the coupling reaction of (a) a saturated or unsaturated cyclic, polycylic, normal or branched chain alkyl, cycloalkyl and spiro-fused and (b) substituted aromatic esters or ketones wherein (a) or (b) or both at least have a deuterium atom or a deuterium atom-containing group. These deuterium-based 1,2-dioxetanes may also have electron donating or withdrawing groups at the four-membered peroxide ring. Thus, the added electronic charge and the isotopic hydrogen or isotopic hydrogen-containing group hereof affects the light producing efficiency of 1,2-dioxetanes.
