Check Digit Verification of cas no
The CAS Registry Mumber 114649-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,6,4 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 114649-82:
(8*1)+(7*1)+(6*4)+(5*6)+(4*4)+(3*9)+(2*8)+(1*2)=130
130 % 10 = 0
So 114649-82-0 is a valid CAS Registry Number.

Synthesis of Linearly Fused 2,8-Dialkyl-4,6-dioxo-4H,6H-benzodipyrans
Reddy, K. Chandraprakash,Srimannarayana, G.
, p. 766 - 767 (2007/10/02)
2,8-Diethyl/dipropyl-4,6-dioxo-4H,6H-benzodipyran (IVa,b) have been prepared by Claisen condensation of 5-acetyl-2,4-dihydroxyacetophenone (I) with ethyl butyrate and ethyl propionate respectively followed by acid-catalyzed cyclization of the resulting diketone (IIIa,b) with conc HCl.Claisen condensation of 2,4-dihydroxy-5-propionylpropiophenone (V) with ethyl butyrate and ethyl propionate furnishes 2,8-dipropyl-(VIa)- and 2,8-diethyl-(VIb)-3,7-dimethyl-4,6-dioxo-4H,6H-benzodipyrans respectively.
