88223-89-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88223-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,2 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 88223-89:
(7*8)+(6*8)+(5*2)+(4*2)+(3*3)+(2*8)+(1*9)=156
156 % 10 = 6
So 88223-89-6 is a valid CAS Registry Number.

CLAISEN REARRANGEMENTS-XIII SYNHESIS OF THE NATURAL COUMARINS, NORDENTATIN, DENTATIN AND CLAUSARIN

Murray, R. D. H.,Jorge, Z. D.

, p. 3133 - 3136 (2007/10/02)

The structure of the natural coumarin, clausarin 10 has been confirmed by an eight step synthesis from 5-hydroxyseselin 1 in 56percent overall yield.The efficient synthesis of its precursor, nordentatin 5 provides a convenient alternative synthetic route to dentatin 6.The revised structure 13 is suggested for clausenidinaric acid.

Efficient syntheses of the coumarins, nordentatin, dentatin and clausarin

Murray,Jorge

, p. 3773 - 3774 (2007/10/02)

A convenient synthetic route to the linear pyranocoumarins, nordentatin (5) and dentatin (6), has been established. A novel out-of-ring Claisen rearrangement has been employed in the synthesis of clausarin (10). The structure of clausenidinaric acid has been reassigned as 11.
