Check Digit Verification of cas no

The CAS Registry Mumber 254428-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,4,2 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 254428-28:
(8*2)+(7*5)+(6*4)+(5*4)+(4*2)+(3*8)+(2*2)+(1*8)=139
139 % 10 = 9
So 254428-28-9 is a valid CAS Registry Number.

Domino Corey-Chaykovsky Reaction for One-Pot Access to Spirocyclopropyl Oxindoles

Hajra, Saumen,Roy, Sayan,Saleh, S.K. Abu

supporting information, p. 4540 - 4544 (2018/08/07)

The development of the sequential Corey-Chaykovsky reactions of isatins, spiroepoxy-, or spiroaziridine oxindoles with sulfur ylide has led to the discovery of a unique reaction mode that allows easy and direct one-pot access to a range of spirocyclopropyl oxindoles.

Reactivity of spiroanthraceneoxazolidines with cyclopropanes: An approach to the oxindole alkaloid scaffold

Buev, Evgeny M.,Moshkin, Vladimir S.,Sosnovskikh, Vyacheslav Y.

supporting information, p. 3409 - 3412 (2018/08/20)

The reaction of N-methylspiro[anthracene-oxazolidine] with spiro[cyclopropane-3,3′-indolin]-2-ones in the presence of MgI2 formed the corresponding spiro[pyrrolidine-3,3′-indolin]-2-ones in 42–65% yields. The use of N-benzylspiro[anthracene-oxazolidine] in this reaction led to the formation of a mixture of the corresponding N-methyl- and N-benzylpyrrolidines.
