Manufacturing Process
2,2’-Dibromo-4,4’-dicyano-α,γ-diphenoxypropane (3.0 g) and anhydrous
ethanol (3.0 ml) were dissolved in anhydrous chloroform (40 ml). The solution
was saturated at 0°C with dry hydrogen chloride and set aside for 7 day. The
iminoether hydrochloride which crystallised out, was filtered off and washed
with light petroleum. The solid was added to 12% ammoniacal ethanol (47
c.c.) and the mixture was heated at 60°C for 6 hours. Solution was obtained
after 3 hours and the amidine hydrochloride began to cryistallise. The mixture
was ice-cooled, and the white crystalline solid was filtered off, washed with 2
N hydrochloric acid, and recrystallised twice from 0.5 N hydrochloric acid.2,2'-Dibromo-4,4'-diamidino-α,γ-diphenoxypropane dihydrochloride (2.1 g)

Check Digit Verification of cas no
The CAS Registry Mumber 496-00-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 6 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 496-00:
(5*4)+(4*9)+(3*6)+(2*0)+(1*0)=74
74 % 10 = 4
So 496-00-4 is a valid CAS Registry Number.
