40148-85-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40148-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,4 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40148-85:
(7*4)+(6*0)+(5*1)+(4*4)+(3*8)+(2*8)+(1*5)=94
94 % 10 = 4
So 40148-85-4 is a valid CAS Registry Number.

Mapping the potential energy surface of the tolylcarbene rearrangement in the inner phase of a hemicarcerand

Kerdelhue, Jean-Luc,Langenwalter, Kevin J.,Warmuth, Ralf

, p. 973 - 986 (2003)

Photolysis of p-tolyldiazirine (6) in the inner phase of a hemicarcerand with four butane-1,4-dioxy linker groups (5) in C6D5CD3 at 77 K yields the 5-methylcycloheptatetraene hemicarceplex 5>=3b in 41% together with innerm

Rearrangements of the Isomeric Tolylmethylenes

Chapman, Orville L.,Johnson, Jeffery W.,Mahon, Robert J. Mc,West, Paul R.

, p. 501 - 509 (2007/10/02)

We present evidence for a mechanism in which the isomeric tolylmethylenes interconvert via methylcycloheptatetraene intermediates.Photolysis (>470 nm) of diazo compounds 1-4, matrix isolated in argon at 10 K, generates triplet tolylmethylenes 8-11.Photoly
