Check Digit Verification of cas no
The CAS Registry Mumber 18993-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,9 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18993-24:
(7*1)+(6*8)+(5*9)+(4*9)+(3*3)+(2*2)+(1*4)=153
153 % 10 = 3
So 18993-24-3 is a valid CAS Registry Number.

PROCESS FOR THE MANUFACTURE OF 1,1,1,3,3-PENTACHLOROPROPANE
-
Page/Page column 4, (2008/06/13)
A process for the manufacture of haloalkanes, or more particularly to a process for the manufacture of 1,1,1,3,3-pentachloropropane (HCC-240fa) and/or and/or 1,1,1,3-tetrachloropropane (HCC-250fb). The process includes (a) mixing a catalyst, co-catalyst and a haloalkane starting material under conditions suitable to produce a homogeneous mixture; (b) reacting the homogeneous mixture with a haloalkene and/or alkene starting material under conditions suitable to produce a haloalkane product stream; and (c) recovering a haloalkane product from said product stream.
