88404-95-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88404-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,4,0 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88404-95:
(7*8)+(6*8)+(5*4)+(4*0)+(3*4)+(2*9)+(1*5)=159
159 % 10 = 9
So 88404-95-9 is a valid CAS Registry Number.

Reactivity of 2-Methylene-1,3-dicarbonyl Compounds. Syntheses of 2,2,3-Trisubstituted-3,4-dihydro-2H-pyranobenzopyran-5-ones

Yamauchi, Masashige,Katayama, Sadamu,Watanabe, Toshio

, p. 2887 - 2891 (2007/10/02)

Michael condensation of 2-methylsulfinylmethyl-1,3-dicarbonyl compounds (3) or 2-methylene-1,3-dicarbonyl compounds (4) with 4-hydroxycoumarin (5) at ambient temperature gave 2--1,3-dicarbonyl compounds (6).Treatment of 6 with methanolic hydrogen chloride resulted in the regioselective formation of 2,2,3-trisubstituted-3,4-dihydro-2H-pyranobenzopyran-5-ones.Keywords - 2-methylene-1,3-dicarbonyl compound; 2-methylsulfinylmethyl-1,3-dicarbonyl compound; 2,2,3-trisubstituted-3,4-dihydro-2H-pyranobenzopyran-5-one; regioselective cyclization; Michael condensation
