Check Digit Verification of cas no

The CAS Registry Mumber 90511-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,1 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90511-11:
(7*9)+(6*0)+(5*5)+(4*1)+(3*1)+(2*1)+(1*1)=98
98 % 10 = 8
So 90511-11-8 is a valid CAS Registry Number.

CYCLOBUTANONES FOR THE STEREOSELECTIVE SYNTHESIS OF BIFUNCTIONAL MACROLIDE INTERMEDIATES

Frater, G.,Mueller, U.,Guenther, W.

, p. 1133 - 1136 (1984)

Beckmann fragmentation of the oximes 5 and 6 respectively, which were derived from the cyclobutanones 3 and 4, furnished the bifunctional five carbon units 7 and 8 with ca. 98percent and 91percent stereoselectivity.

Kinetic resolution in the [2+2] cycloaddition of ketenes: An experimental and theoretical study

Rullire, Pauline,Carret, Sbastien,Milet, Anne,Poisson, Jean-Franois

supporting information, p. 3876 - 3881 (2015/10/19)

The kinetic resolution of Z and E olefins by [2+2] cycloaddition with ketenes allows the isolation of pure E olefin, as well as the synthesis of pure cis-cyclobutanones, starting from Z/E mixtures. A computational rationale for this kinetic difference is reported. The obtained difference of energy of activation matches with the experimental results.
