Check Digit Verification of cas no

The CAS Registry Mumber 134891-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,9 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134891-13:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*1)+(2*1)+(1*3)=137
137 % 10 = 7
So 134891-13-7 is a valid CAS Registry Number.

Decarboxylative Nazarov Cyclization-Based Chirality Transfer for Asymmetric Synthesis of 2-Cyclopentenones

Komatsuki, Keiichi,Kozuma, Akane,Saito, Kodai,Yamada, Tohru

supporting information, p. 6628 - 6632 (2019/09/03)

Asymmetric synthesis of 2-cyclopentenones was achieved by chirality transfer based on Lewis acid catalyzed decarboxylative Nazarov cyclization of optically active cyclic enol carbonates, which are prepared by silver-catalyzed carbon dioxide incorporation into optically pure propargyl alcohols. The stereochemistry at the 4,5-positions of the 2-cyclopentenones was cleanly constructed by reflecting the stereochemistry of the starting materials. This method could be applied to various substrates to obtain the corresponding products in high yields with highly efficient chirality transfer.

Palladium-catalysed arylation of allylic alcohols: Highly selective synthesis of β-aromatic carbonyl compounds or β-aromatic α,β-unsaturated alcohols

Jeffery

, p. 2121 - 2124 (2007/10/02)

The outcome of the coupling of aromatic halides with allylic alcohols can be highly controlled and the reaction directed at will towards the forrmation of either β-aromatic carbonyl or β-aromatic αβ-unsaturated alcohol compounds.
