Check Digit Verification of cas no

The CAS Registry Mumber 78426-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,2 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78426-89:
(7*7)+(6*8)+(5*4)+(4*2)+(3*6)+(2*8)+(1*9)=168
168 % 10 = 8
So 78426-89-8 is a valid CAS Registry Number.

PRACTICAL SYNTHESIS OF 2-(6'-METHOXYCARBONYLHEXYL)CYCLOPENT-2-EN-1-ONE (PROSTAGLANDIN SYNTHON)

Lapitskaya, M. A.,Manukina, T. A.,Nozdracheva, A. T.,Sheimina, L. G.,Pivnitskii, K. K.

, p. 261 - 265 (2007/10/02)

2-(6'-Methoxycarbonylhexyl)cyclopentanone was obtained by alkylation of the 2-(ethoxycarbonyl)cyclopentanone potassium salt with diethyl 5-bromopentylmalonate followed by acid cleavage of the obtained triester and esterification.Its bromination with copper bromide and dehydrobromination with collidine lead to 2-(6'-methoxycarbonylhexyl)cyclopent-2-en-1-one (a known prostaglandin synthon) with an overall yield of 28percent.The use of molecular bromine for bromination leads to the production of the 5-bromo analog of the synthon.
