Check Digit Verification of cas no

The CAS Registry Mumber 40524-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,2 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40524-62:
(7*4)+(6*0)+(5*5)+(4*2)+(3*4)+(2*6)+(1*2)=87
87 % 10 = 7
So 40524-62-7 is a valid CAS Registry Number.

Palladium-Catalyzed Synthesis of α-Methyl Ketones from Allylic Alcohols and Methanol

Biswal, Priyabrata,Samser, Shaikh,Meher, Sushanta Kumar,Chandrasekhar, Vadapalli,Venkatasubbaiah, Krishnan

supporting information, p. 413 - 419 (2021/11/01)

One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through a hydrogen-borrowing pathway in these isomerization-methylation reactions.

A new method for the synthesis of chalcone derivatives promoted by PPh3/I2under non-alkaline conditions

Xue, Kangsheng,Sun, Guoxiang,Zhang, Yanzhi,Chen, Xubing,Zhou, Yang,Hou, Jinjun,Long, Huali,Zhang, Zijia,Lei, Min,Wu, Wanying

supporting information, p. 625 - 634 (2020/11/23)

A straightforward and general method has been developed for the synthesis of chalcone derivatives by a Claisen-Schmidt reaction in the presence of PPh3/I2 in 1,4-dioxane under reflux temperatures. With the condensation of the aromatic ketone and aldehyde occurring at non-strongly alkaline conditions, our proposed method significantly expands the range of applicable substrates, especially for groups that are unstable under alkaline conditions.

Organo-catalyzed Michael addition of 2-fluoro-2-arylacetonitriles

Chen, De-Yin,Song, Shuai,Chen, Ling-Yan,Ren, Xinfeng,Li, Ya

supporting information, (2021/03/01)

An efficient synthesis of a variety of 2-arylacetonitriles containing a fluorinated stereogenic center through organo-catalyzed Michael addition reaction of 2-fluoro-2-arylacetonitriles has been developed. This protocol uses a cheap organocatalyst (DBU) and has a broad substrate scope: α, β-unsaturated ketones, esters, nitriles and sulfones were all successfully reacted. Importantly, water proved to be a good solvent for this reaction.
