97457-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97457-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,4,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97457-31:
(7*9)+(6*7)+(5*4)+(4*5)+(3*7)+(2*3)+(1*1)=173
173 % 10 = 3
So 97457-31-3 is a valid CAS Registry Number.

STRUCTURE DETERMINATION OF CANDIDINE, A VIOLET INDOLIC CONSTITUENT FROM CULTURE SOLUTIONS OF CANDIDA LIPOLYTICA

Bergman, Jan,Tilstam, Ulf

, p. 2883 - 2884 (1985)

A violet indolic constituent, candidine, isolated from culture solutions of Candida lipolytica has been identified as 6,12-dihydro-6-(3-oxoindolid-2-ene)-12-oxoindoloquinazoline by an independent synthesis (condensation of 6,12-dihydro-6,12-dioxoindoloquinazoline with 1-acetylindoxyl).

One-pot synthesis of tryptanthrin by the Dakin oxidation of indole-3-carbaldehyde

Abe, Takumi,Itoh, Tomoki,Choshi, Tominari,Hibino, Satoshi,Ishikura, Minoru

, p. 5268 - 5270 (2015/01/09)

A one-pot approach to indolo[2,1-b]quinazolines from indole-3-carbaldehydes through the Dakin oxidation was developed. It was shown that the reaction proceeded through the condensation of indole-3-carbaldehydes with isatoic anhydrides, derived in situ from indole-3-carbaldehydes by the Dakin oxidation, and further oxidation/cyclization steps.
