Check Digit Verification of cas no
The CAS Registry Mumber 13522-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,2 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13522-31:
(7*1)+(6*3)+(5*5)+(4*2)+(3*2)+(2*3)+(1*1)=71
71 % 10 = 1
So 13522-31-1 is a valid CAS Registry Number.

Preparation of catechol derivatives
-
, (2008/06/13)
A method of preparing derivatives of aromatic compounds including the catechol function STR1 by replacement of one of the hydroxyls by mercaptan STR2 Cathechol or a multi-ring compound (naphthyl-, anthryl-, phenanthryl-, etc.) containing the catechol function is first reacted with thiophosgene to produce the corresponding dioxole-2-thione STR3 The thione is ammonolyzed to the corresponding hydroxy N,N-disubstituted thionocarbamate STR4 The thionocarbamate is acetylated to STR5 and heated to rearrange the compound to the corresponding thiolcarbamate STR6 Further heating produces the corresponding oxathiol-2-one STR7 which can be hydrolyzed to the corresponding mercaptan STR8
