Check Digit Verification of cas no

The CAS Registry Mumber 60314-07-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,3,1 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 60314-07:
(7*6)+(6*0)+(5*3)+(4*1)+(3*4)+(2*0)+(1*7)=80
80 % 10 = 0
So 60314-07-0 is a valid CAS Registry Number.

Process for producing rhein and diacerhein

-

, (2008/06/13)

The following description sets forth a process for producing rhein, diacerhein and other diacyl derivatives thereof, which comprises the following steps: treatment of a diphenylketone STR1 in which R1 is --OR', --NR'R", --SR', where R' and R" are H, an alkyl or aromatic group; R2 is H or a protective group, R3 is --OH or C1 -C4 alkyl, with an acid or superacid to give a 1-aminoanthraquinone derivative, diazotisation, replacement of the --NH2 group by --OH, optional removal of the protective group, and acylation.

Facile Interconversion of the Isomeric Acid Chlorides Derived from Half Methyl Esters of 3-Methoxyphthalic Acid

Gupta, Dahmendra N.,Hodge, Philip,Hurley, Peter N.

, p. 391 - 394 (2007/10/02)

The isomeric acid chlorides obtained by treating the half methyl esters of 3-methoxyphthalic acid with thionyl chloride interconvert so readily that it is not practical to isolate one acid chloride free of the other.At equilibrium the main isomer is the a
