Check Digit Verification of cas no

The CAS Registry Mumber 1018683-94-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,8,6,8 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1018683-94:
(9*1)+(8*0)+(7*1)+(6*8)+(5*6)+(4*8)+(3*3)+(2*9)+(1*4)=157
157 % 10 = 7
So 1018683-94-7 is a valid CAS Registry Number.

1,3-Dipolar cycloaddition of N-substituted dipolarophiles and nitrones: Highly efficient solvent-free reaction

Thanh, Binh Nguyen,Martel, Arnaud,Dhal, Robert,Dujardin, Gilles

, p. 2621 - 2632 (2008/09/19)

(Chemical Equation Presented) New isoxazolidines were synthesized in good to excellent yields by 1,3-dipolar cycloaddition of N-vinylamide dipolarophiles and nitrones. Strikingly, solvent-free conditions gave high conversion and yields, shortened reaction time, and minimized degradation products. N-Vinyloxazolidin-2-one and its analogues used in these cycloaddition reactions were conveniently prepared in excellent yields by a modified version of Buchwald's one-step copper-catalyzed vinylation using vinyl bromide. From the adducts, a two-step access to various unsymmetric aspartate derivatives was also described.
