Check Digit Verification of cas no
The CAS Registry Mumber 83612-48-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,1 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83612-48:
(7*8)+(6*3)+(5*6)+(4*1)+(3*2)+(2*4)+(1*8)=130
130 % 10 = 0
So 83612-48-0 is a valid CAS Registry Number.

Methyleneketenes and Methylenecarbenes. XVII Generation of Methyleneketene Intermediates by Pyrolysis of N-Alkenoylpyrazoles and Synthesis of Simple Phenols

Flash vacuum pyrolysis of 1-acyl-3,5-dimethylpyrazoles forms ketenes, but the conditions may lead to decarbonylation of the ketene.The 1-cinnamoyl derivative (4) forms phenylacetylene at 750 deg/0.02 mm, via benzylideneketene and benzylidenecarbene.Simple phenols (2-naphthol, phenol, 4-methylphenol, 2,4-dimethylphenol, and 3,5-dimethylphenol) are obtained in high yield on pyrolysis of the appropriate dienoylpyrazoles (10), (13), (16), (18) and (21); the reaction proceeds by way of cyclization of dienylketenes.
