Check Digit Verification of cas no

The CAS Registry Mumber 131447-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,4 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131447-45:
(8*1)+(7*3)+(6*1)+(5*4)+(4*4)+(3*7)+(2*4)+(1*5)=105
105 % 10 = 5
So 131447-45-5 is a valid CAS Registry Number.

SYNTHESIS OF 4-CHLORO-7-DIALKYLAMINOCOUMARINS

Kirpichenok, M. A.,Gorozhankin, S. K.,Grandberg, I. I.

, p. 693 - 697 (2007/10/02)

A series of 4-chloro-7-dialkylaminocoumarins has been synthesized by heating m-diethylaminophenol, m-N-piperidinophenol, m-N-morpholinophenol, and 8-hydroxyjulolidine, respectively, with malonic acids in the presence of excess phosphorus oxychloride.The feasibility of preparing other 4-substituted 7-aminocoumarins from these 4-chloro derivatives has been demonstrated using as an example the reactions of 4-chloro-7-diethylaminocoumarins with sodium ethoxide, hydrazine, and dibutylamine.The spectral and luminescence characteristics of these newly synthesized compounds have been investigated.
