Check Digit Verification of cas no
The CAS Registry Mumber 5238-65-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,3 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5238-65:
(6*5)+(5*2)+(4*3)+(3*8)+(2*6)+(1*5)=93
93 % 10 = 3
So 5238-65-3 is a valid CAS Registry Number.

Method of producing hexamethylene diamine from butadiene
-
Page/Page column 3, (2008/06/13)
The invention relates to the production of hexamethylene diamine from butadiene. The method comprises the successively performed stages of: (i) a catalytic epoxidation of butadiene to 1,2-epoxy-3-butene; (ii) a basically catalyzed addition of hydrogen cyanide to butadiene monoxide to form a reaction mixture containing 3-hydroxy-4-pentene nitrile (3HPN) and 2-hydroxymethyl-3-butene nitrile (2HMBN); (iii) an acidically catalyzed dehydration of the cyanohydrines 3HPN and 2HMBN of stage (ii) to cis/trans-pentadiene nitrile (PDN); (iv) a basically catalyzed addition of the products of stage (iii) to form cis/trans-1,4-dicyanobutene-1 and -2 (DCB); and (v) a catalytic hydrogenation of the isomeric cis/trans-1,4-dicyanobutene of stage (iv) to hexamethylene diamine.
