Check Digit Verification of cas no

The CAS Registry Mumber 80522-97-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,2 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80522-97:
(7*8)+(6*0)+(5*5)+(4*2)+(3*2)+(2*9)+(1*7)=120
120 % 10 = 0
So 80522-97-0 is a valid CAS Registry Number.

UNPRECEDENTED REARRANGEMENTS VIA ALLENES AS ?-PARTICIPANTS IN α-ACYLIMINIUM ION CYCLISATIONS

Nossin, Peter M. M.,Speckamp, W. Nico

, p. 3289 - 3292 (1981)

Upon HCOOH reaction of ethoxylactams 1a-1d the terminally unsubstituted allenes 1a and 1d underwent a sigmatropic rearrangement.The dimethyl allenes 1b and 1c afforded only products from an α-acyliminium ion cyclisation.
