Check Digit Verification of cas no

The CAS Registry Mumber 122021-65-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,2 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 122021-65:
(8*1)+(7*2)+(6*2)+(5*0)+(4*2)+(3*1)+(2*6)+(1*5)=62
62 % 10 = 2
So 122021-65-2 is a valid CAS Registry Number.

1,3-Dipolar Cycloaddition of Nitrones with Nitriles. Scope and Mechanistic Study

Hermkens, Pedro H.H.,Maarseveen, Jan H. v.,Kruse, Chris G.,Scheeren, Hans W.

, p. 6491 - 6504 (2007/10/02)

1,3-Dipolar cycloadditions of nitrones 1-6 with nitriles 14-16, proceeded under thermal as well as under high pressure conditions with complete regioselectivity to give Δ4-1,2,4-oxadiazolines 17-19.In general, the cycloaddition seemed to be controlled by a HOMO(nitrone)- LUMO(nitrile) interaction.However, a crossover in the orbital control is probable observed with nitrile 16c.Nitrone-nitrile cycloadditions are normal type II cycloadditions so that the nitriles have a U-shaped reactivity curve.Kinetic study on solvent polarity and Hammett equation demonstrated that mechanistically the nitrone-nitrile cycloaddition is consistent with nitrone-alkene cycloaddition.
