267005-80-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 267005-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,0,0 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 267005-80:
(8*2)+(7*6)+(6*7)+(5*0)+(4*0)+(3*5)+(2*8)+(1*0)=131
131 % 10 = 1
So 267005-80-1 is a valid CAS Registry Number.

Fluorinated Musk Fragrances: The CF2Group as a Conformational Bias Influencing the Odour of Civetone and (R)-Muscone

Callejo, Ricardo,Corr, Michael J.,Yang, Mingyan,Wang, Mingan,Cordes, David B.,Slawin, Alexandra M. Z.,O'Hagan, David

, p. 8137 - 8151 (2016)

The difluoromethylene (CF2) group has a strong tendency to adopt corner over edge locations in aliphatic macrocycles. In this study, the CF2group has been introduced into musk relevant macrocyclic ketones. Nine civetone and five muscone analogues have been prepared by synthesis for structure and odour comparisons. X-ray studies indeed show that the CF2groups influence ring structure and they give some insight into the preferred ring conformations, triggering a musk odour as determined in a professional perfumery environment. The historical conformational model of Bersuker and co-workers for musk fragrance generally holds, and structures that become distorted from this consensus, by the particular placement of the CF2groups, lose their musk fragrance and become less pleasant.

Streamlined One-Pot Synthesis of Nitro Fatty Acids

El Rady, Eman A.,Hassan, Mohamed,Krieg, Sara-Cathrin,Maier, Thorsten J.,Manolikakes, Georg,Ndefo Nde, Cedric,Raslan, Mohamed A.,Roos, Jessica,Sadek, Kamal U.

, p. 2239 - 2252 (2021/07/22)

A novel method for the synthesis of nitro fatty acids (NFAs), an intriguing class of endogenously occurring lipid mediators, is reported. This one-pot procedure enables the controlled and stereoselective construction of nitro fatty acids from a simple set of common building blocks in a highly facile manner. Thereby, this methodology offers a streamlined, highly modular access to naturally occurring nitro fatty acids as well as non-natural NFA derivatives.

A chemoenzymatic asymmetric synthesis of (9S,12S,13S)- and (9S,12RS,13S)-pinellic acids

Sharma, Anubha,Mahato, Seema,Chattopadhyay, Subrata

scheme or table, p. 4986 - 4988 (2009/12/03)

A brief and facile synthesis of the title compounds has been developed by using an efficient lipase-catalyzed acylation and a chiral template-directed diastereoselective alkylation for incorporating the stereogenic centres. A cross-metathesis was employed to get the required E-olefin geometry.
