Check Digit Verification of cas no

The CAS Registry Mumber 293759-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,3,7,5 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 293759-04:
(8*2)+(7*9)+(6*3)+(5*7)+(4*5)+(3*9)+(2*0)+(1*4)=183
183 % 10 = 3
So 293759-04-3 is a valid CAS Registry Number.

Synthesis of 2-amino-4-aryl-5-oxo-4,5-dihydropyrano[3,2-c] chromene derivatives catalysed by KF-montmorillonite

Shi, Da-Qing,Wu, Nan,Zhuang, Qi-Ya

, p. 542 - 545 (2008)

A series of 2-amino-4-aryl-5-oxo-4,5-dihydropyrano[3,2-c]chromene derivatives has been synthesised by the reaction of 4-hydroxycoumarin and substituted cinnamonitriles catalysed by KF-montmorillonite. The structures were characterised by IR and 1/su
