1415908-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1415908-44-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,5,9,0 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1415908-44:
(9*1)+(8*4)+(7*1)+(6*5)+(5*9)+(4*0)+(3*8)+(2*4)+(1*4)=159
159 % 10 = 9
So 1415908-44-9 is a valid CAS Registry Number.

Synthesis and fluorescence study of 6,7-diaminocoumarin and its imidazolo derivatives
Sheshashena Reddy,Ram Reddy
, p. 525 - 534 (2013)
Novel 6,7-diamino-4-methylcoumarin and derived imidazolocoumarins were synthesized and their absorption and fluorescence properties were recorded in solvents of varying polarity. 6,7-Diamino-4-methylcoumarin is highly fluorescent, with a quantum yield of
