Check Digit Verification of cas no

The CAS Registry Mumber 105397-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,3,9 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 105397-59:
(8*1)+(7*0)+(6*5)+(5*3)+(4*9)+(3*7)+(2*5)+(1*9)=129
129 % 10 = 9
So 105397-59-9 is a valid CAS Registry Number.

THE FLOW THERMOLYSES OF 1-ISOBUTENYL ALKYNYL- AND 2-METHYLPHENYL ALKYNYL KETONES. SYNTHESIS OF METHYLENOMYCIN B

Koller, Manuel,Karpf, Martin,Dreiding, Andre S.

, p. 19 - 22 (2007/10/02)

The gas flow thermolyses of 1-isobutenyl alkynyl and 2-methylphenyl alkynyl ketones were found to lead to phenols and to cyclopentenones.The results are explained by a 5-ring carbene process (the known α-alkynone cyclization) and a 6-ring as well as a 5-ring addition process.The latter two (novel) processes are thought to be intramolecular "C-H to CC additions" in two directions.The 5-ring addition process was used in a short (but low yield) synthesis of methylenomycin B.
