Check Digit Verification of cas no

The CAS Registry Mumber 1258636-22-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,6,3 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1258636-22:
(9*1)+(8*2)+(7*5)+(6*8)+(5*6)+(4*3)+(3*6)+(2*2)+(1*2)=174
174 % 10 = 4
So 1258636-22-4 is a valid CAS Registry Number.

Synthesis of 1,2-disubstituted cyclopentenes by palladium-catalyzed reaction of homopropargyl-substituted dicarbonyl compounds with organic halides via 5- endo-dig cyclization

Fujino, Daishi,Yorimitsu, Hideki,Osuka, Atsuhiro

, p. 2914 - 2917 (2012/07/28)

Palladium catalysts with bulky biaryl phosphine ligands allow homopropargyl-substituted dicarbonyl compounds to undergo intramolecular addition via a rare 5-endo-dig pathway. C-C bond forming reductive elimination follows the addition to introduce alkenyl and alkynyl as well as aryl groups by using the corresponding organic halides. The cyclization is versatile enough to be applicable to the synthesis of highly substituted dihydropyrrole and a fused tricyclic compound.
