71796-68-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71796-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,9 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71796-68:
(7*7)+(6*1)+(5*7)+(4*9)+(3*6)+(2*6)+(1*8)=164
164 % 10 = 4
So 71796-68-4 is a valid CAS Registry Number.

Oxidative rearrangement of 2-alkoxy-3,4-dihydro-2H-pyrans: stereocontrolled synthesis of 4,5-cis-disubstituted tetrahydrofuranones including whisky and cognac lactones and crobarbatic acid

Armstrong, Alan,Ashraff, Cassim,Chung, Hunsuk,Murtagh, Lorraine

experimental part, p. 4490 - 4504 (2009/10/09)

Oxidation of 2-alkoxy-3,4-dihydro-2H-pyrans 3 with dimethyldioxirane or MTO/urea-H2O2 followed by Jones oxidation leads to rearrangement and stereocontrolled formation of 4,5-cis-disubstituted tetrahydrofuranones. The method is applied to the synthesis of the whisky lactone 9, cognac lactone 10 and crobarbatic acid 17.
