The CAS Registry Mumber 1239703-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,7,0 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1239703-01:
(9*1)+(8*2)+(7*3)+(6*9)+(5*7)+(4*0)+(3*3)+(2*0)+(1*1)=145
145 % 10 = 5
So 1239703-01-5 is a valid CAS Registry Number.

Pentamethine Cyanine Fluorescent Dye with N-substituting at Beta-Position of Conjugated Chain

-

Page/Page column 3-4, (2012/12/13)

A pentamethine cyanine fluorescent dye with N-substituting at β-position of conjugated chain is disclosed. The dye reacts with biosubstrate including protein, liposome and DNA, and shows excellent selectivity. It has good living cell membrane permeability and shows good selectivity in living cell staining In addition, the dye has good stability and low background fluorescence, and can be used together with other fluorescent dyes having consistent wavelengths for single-channel excitation and multi-channel detection. The dye can be used in the fields of protein labeling and detecting, fluorescence immunoassay and living cell selective imaging and the like.
