Check Digit Verification of cas no

The CAS Registry Mumber 112840-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112840-18:
(8*1)+(7*1)+(6*2)+(5*8)+(4*4)+(3*0)+(2*1)+(1*8)=93
93 % 10 = 3
So 112840-18-3 is a valid CAS Registry Number.

Study of the Thermal Transformation of 5-exo-Methyleneisoxazolidines to 3-Pyrrolidinones

Padwa, Albert,Matzinger, Michael,Tomioka, Yukihiko,Venkatramanan, M. K.

, p. 955 - 963 (2007/10/02)

Dipolar cycloaddition of nitrones with electron-deficient allenes gives 5-exo-methylene substituted isoxazolidines in high yield.The regiochemistry of the cycloaddition can be attributed to a favorable allene (LUMO)-nitrone (HOMO) interaction.The isoxazol
