Check Digit Verification of cas no

The CAS Registry Mumber 153476-59-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,4,7 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 153476-59:
(8*1)+(7*5)+(6*3)+(5*4)+(4*7)+(3*6)+(2*5)+(1*9)=146
146 % 10 = 6
So 153476-59-6 is a valid CAS Registry Number.

Preparation and Reactivity of New β-Nitrogen-Functionalized Vinylic Organolithium Compounds from Secondary Aliphatic Allylamines

Barluenga, Jose,Canteli, Rosa-Maria,Florez, Josefa

, p. 602 - 606 (2007/10/02)

Two new types of β-nitrogen-functionalized vinylic organolithium compounds have been prepared from secondary aliphatic allylamines through the temporary silylation of the amino group.The monoanionic intermediates 4, stable at -80 deg C, are generated by a bromine-lithium exchange reaction and the dianionic derivatives 2, stable at room temperature, by a tin-lithium transmetalation reaction.Both types of organolithium compounds react with different electrophiles giving functionalized allylamines 7 and 10-27.Moreover, dianionic derivatives 30,33 can be prepared directly by bromine-lithium exchange when the β-elimination reaction of hydrogen bromide in the lithium 2-bromoallylamide is structurally hindered.Additionally, a novel type of anionic 1,3-rearrangement of a trimethylsilyl group from nitrogen to carbon is described.
