178156-34-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 178156-34-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,1,5 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 178156-34:
(8*1)+(7*7)+(6*8)+(5*1)+(4*5)+(3*6)+(2*3)+(1*4)=158
158 % 10 = 8
So 178156-34-8 is a valid CAS Registry Number.

Syntheses and properties of water-soluble Nile Red derivatives
Jose, Jiney,Burgess, Kevin
, p. 7835 - 7839 (2007/10/03)
(Chemical Equation Presented) Nile Red (compound A) fluoresces at about 530 nm with good quantum yields in apolar solvents. In more polar ones its fluorescence emission shows a dramatic, and potentially useful, shift to about 640 nm, but its quantum yield
