131779-79-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131779-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,7,7 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131779-79:
(8*1)+(7*3)+(6*1)+(5*7)+(4*7)+(3*9)+(2*7)+(1*9)=148
148 % 10 = 8
So 131779-79-8 is a valid CAS Registry Number.

Nickel-Catalyzed Desymmetrizing Cross-Electrophile Coupling of Cyclic Meso-Anhydrides

Lin, Tingzhi,Mi, Jianjun,Song, Lichao,Gan, Jiamin,Luo, Pan,Mao, Jianyou,Walsh, Patrick J.

supporting information, p. 1191 - 1194 (2018/02/22)

A Ni-catalyzed desymmetrizing cross-electrophile coupling of cyclic meso-anhydrides with aryl triflates has been successfully demonstrated. This is the only example using cyclic meso-anhydrides in cross-electrophile coupling reactions. A diverse array of valuable γ-keto acid building blocks can be generated under these conditions with excellent functional group tolerance and stereochemical fidelity.

A Stereoselective Synthesis of a Basic Skeleton of Amaryllidaceae Montanine-type Alkaloids, (+/-)-4a,11a-cis-11,11a-syn-5,11-Methanomorphanthridine Ring System

Hoshino, Osamu,Ishizaki, Miyuki

, p. 1817 - 1820 (2007/10/02)

A title compound was synthesized by reductive cyclization of 4a,11a-cis-11,11a-syn-11-acetoxymethyl-N-p-tosylmorphanthridine or N-detosylated alcohol derived from a hydroxymethyl-p-tosylamide prepared by hydroboration-oxidation of cis-1-(p-tosylamido)-2-v
