Calculate Digit Verification of CAS Registry Number 1403692-31:
(9*1)+(8*4)+(7*0)+(6*3)+(5*6)+(4*9)+(3*2)+(2*3)+(1*1)=138
138 % 10 = 8

Synthesis of new 8-formyl-4-methyl-7-hydroxy coumarin derivatives

Manidhar,Rao, K. Uma Maheswara,Reddy, N. Bakthavatchala,Sundar, Ch. Syama,Reddy, C. Suresh

, p. 459 - 463 (2012/11/07)

8-Formyl-4-Methyl-7-Hydroxy Coumarin Derivatives were synthesized via Penchem condensation followed by Duffs reaction. Treatment of this with N,N-di substituted cyano acetamides in the presence of piperdine afforded New 8- Formyl-4-Methyl-7-Hydroxy Coumarin Derivatives (7a-o). Their structures were characterized by IR, 1H and 13C NMR and Mass spectral and elemental analysis data.
