Check Digit Verification of cas no

The CAS Registry Mumber 54639-85-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,3 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54639-85:
(7*5)+(6*4)+(5*6)+(4*3)+(3*9)+(2*8)+(1*5)=149
149 % 10 = 9
So 54639-85-9 is a valid CAS Registry Number.

Evidence for the Mechanism of Formation of N-(1,2-Dihydrobenzocyclobut-1-enyl)pyridinium Bromides and Acetophenones from Bis-dibromocyclopropane Adducts

Yagoub, Ahmed K.,Iskander, George M.

, p. 2405 - 2407 (2007/10/02)

The bis-dibromocarbene adducts (1a-e) when boiled with xylene in the presence of 1,4-diazabicyclooctane gave the corresponding bicyclo-octadienes (2a-e).These except for (2d,e) invariably gave the pyridinium salts (3) with boiling pyridine.Besides,
