Check Digit Verification of cas no
The CAS Registry Mumber 6156-18-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,5 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6156-18:
(6*6)+(5*1)+(4*5)+(3*6)+(2*1)+(1*8)=89
89 % 10 = 9
So 6156-18-9 is a valid CAS Registry Number.

IMPROVED PROCESS FOR THE MANUFACTURE OF POLYPHENOLS
-
Page/Page column 20-21, (2008/06/13)
An improved process for the manufacture of a polyphenol compound such as bisphenol-A by introducing into a reaction zone a phenolic compound reactant, a carbonyl compound reactant, and a catalyst promoter comprising bismethylthiopropane added to the reaction system in certain specific locations, and reacting the ingredients within the reaction zone in the presence of an acid catalyst.
