535921-08-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 535921-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,5,9,2 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 535921-08:
(8*5)+(7*3)+(6*5)+(5*9)+(4*2)+(3*1)+(2*0)+(1*8)=155
155 % 10 = 5
So 535921-08-5 is a valid CAS Registry Number.

Efficient synthesis of trisubstituted [1]benzopyrano[4,3-b]pyrrol-4(1H)-one derivatives from 4-hydroxycoumarin

Liao, Yuan-Xiu,Kuo, Pei-Yu,Yang, Ding-Yah

, p. 1599 - 1602 (2007/10/03)

Various trisubstituted [1]benzopyrano[4,3-b]pyrrol-4(1H)-one derivatives have been synthesized from 4-hydroxycoumarin with a 30-40% yield over six steps. The key step of the synthesis is a base-promoted intramolecular cyclization of enamines 5, followed by dehydration to generate the fused pyrrole ring.
