Check Digit Verification of cas no

The CAS Registry Mumber 219740-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219740-90:
(8*2)+(7*1)+(6*9)+(5*7)+(4*4)+(3*0)+(2*9)+(1*0)=146
146 % 10 = 6
So 219740-90-6 is a valid CAS Registry Number.

Nickel powder promoted 5-endo radical cyclisations. A concise approach to erythrina alkaloids

Cassayre, Jerome,Quiclet-Sire, Beatrice,Saunier, Jean-Baptiste,Zard, Samir Z.

, p. 8995 - 8998 (1998)

N-Alkenyl trichloroacetamides 3 undergo, upon refluxing with nickel powder and acetic acid in 2-propanol, exclusive 5-endo-trig cyclisation to afford functionalised lactams 4; these are attractive precursors of erythrina alkaloids, as demonstrated by the expedient synthesis of 3- demethoxyerythratidinone 5.
