Check Digit Verification of cas no
The CAS Registry Mumber 287-97-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 287-97:
(5*2)+(4*8)+(3*7)+(2*9)+(1*7)=88
88 % 10 = 8
So 287-97-8 is a valid CAS Registry Number.

Preparation of hexenedioic acid diesters
-
, (2008/06/13)
Hexene-1,6-dioates, readily hydrogenated into adipates (which in turn are conveniently hydrolyzed into adipic acid), are prepared by reacting carbon monoxide, an alcohol and at least one dichlorobutene, in the presence of a catalytically effective amount of palladium or a palladium compound and no more than two equivalents (relative to the dichlorobutene) of a tertiary amine reaction promoter; in an alternate embodiment, the tertiary amine and the dichlorobutene are first converted into a quaternary ammonium chloride intermediate.
