Check Digit Verification of cas no

The CAS Registry Mumber 71766-58-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,6 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71766-58:
(7*7)+(6*1)+(5*7)+(4*6)+(3*6)+(2*5)+(1*8)=150
150 % 10 = 0
So 71766-58-0 is a valid CAS Registry Number.

Thermal rearrangement of halogenated dimethylenecyclobutane and methylenecyclobutene derivatives

Charrouf-Chafchaouni, Zoubida,Maurin, Robert,Guillaume, Dominique

, p. 5099 - 5102 (1996)

Upon heating, dichlorodimethylenecyclobutanes (1, 2, 18) undergo rearrangements that yield benzene derivatives including styrene adducts. Preparation of postulated intermediates (10, 23) and study of their pyrolytic behaviour allow to unambiguously establish the mechanism of formation of the styrene derivatives.
