Check Digit Verification of cas no

The CAS Registry Mumber 1295569-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,5,5,6 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1295569-18:
(9*1)+(8*2)+(7*9)+(6*5)+(5*5)+(4*6)+(3*9)+(2*1)+(1*8)=204
204 % 10 = 4
So 1295569-18-4 is a valid CAS Registry Number.

Synthesis of indenoindene-fused α-methylene-γ-butyrolactones via a tandem intra- and intermolecular Friedel-Crafts reaction

Park, Bo Ram,Kim, Se Hee,Kim, Yu Mi,Kim, Jae Nyoung

, p. 1700 - 1704 (2011)

An efficient synthesis of indenoindene-fused α-methylene-γ- butyrolactones was carried out via a tandem intra- and intermolecular Friedel-Crafts reaction from the spiro-lactone, which can be easily prepared from ninhydrin by indium-mediated Barbier reaction of cinnamyl bromide.
