Check Digit Verification of cas no
The CAS Registry Mumber 155863-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,6 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155863-33:
(8*1)+(7*5)+(6*5)+(5*8)+(4*6)+(3*3)+(2*3)+(1*3)=155
155 % 10 = 5
So 155863-33-5 is a valid CAS Registry Number.

Syntheses of Reactive Fluorescent Stains Derived from 5(2)-Aryl-2(5)-(4-pyridyl)oxazoles and Bifunctionally Reactive Linkers
Litak, Peter T.,Kauffman, Joel M.
, p. 457 - 480 (2007/10/02)
Several bifunctionally reactive linkers containing halide or sulfonate ester groups were prepared.The linkers were used to quaternize 5-(4-methoxyphenyl)-2-(4-pyridyl)oxazole and 2-(6-chromanyl)-5-(4-pyridyl)oxazole to produce fluorescent stains that contained a reactive group such as an isothiocyanate, an N-hydroxysuccinimidyl ester, a maleimide, or an oxirane.The stains were derivatized with either 1-propyl-amine, 1-propanethiol, or piperidine, as appropriate, to help in characteriazation.The stains may serve as more photostable alternatives to fluoresceins or coumarins.
