Check Digit Verification of cas no
The CAS Registry Mumber 21581-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21581-41:
(7*2)+(6*1)+(5*5)+(4*8)+(3*1)+(2*4)+(1*1)=89
89 % 10 = 9
So 21581-41-9 is a valid CAS Registry Number.

Synthesis of 5-hydroxyoxaindan-2-ones and indol-5-ols from 1,4- cyclohexanedione
Ozaki, Yutaka,Quan, Zhe-Shan,Watabe, Kyouko,Kim, Sang-Won
, p. 727 - 731 (2007/10/03)
1,4-Cyclohexanedione reacted with 2-oxocarboxylic acids to give 5- hydroxyoxaindan-2-ones including homogentisic lactone in one pot. The obtained aromatic compounds were transformed into indol-5-ols in a few steps. The sequential reactions showed a significance of 1,4-cyclohexanedione as a starting material in aromatic synthesis and an alternative access to the indol-5-ols.
