Check Digit Verification of cas no

The CAS Registry Mumber 80206-52-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,0 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80206-52:
(7*8)+(6*0)+(5*2)+(4*0)+(3*6)+(2*5)+(1*2)=96
96 % 10 = 6
So 80206-52-6 is a valid CAS Registry Number.

One-Pot Nonphotochemical Synthesis of Dewar Pyridones from Alkynes and Isocyanates

Hogeveen, H.,Kok, D. M.

, p. 997 - 1001 (1982)

A one-pot synthesis of substituted 3-oxo-2-azabicyclohex-5-enes (Dewar pyridones) from alkynes, aluminum halides, and isocyanates is described.The mechanism of the reaction of isocyanates with the intermediate aluminum halide ? complexes of cyclobutadienes is discussed on the basis of the substitution pattern of the obtained bicyclic products.The thermal and acid-promoted reactions of some of the compounds are reported.
