Check Digit Verification of cas no

The CAS Registry Mumber 52240-18-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 52240-18:
(7*5)+(6*2)+(5*2)+(4*4)+(3*0)+(2*1)+(1*8)=83
83 % 10 = 3
So 52240-18-3 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.
