Check Digit Verification of cas no

The CAS Registry Mumber 15120-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,2 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15120-47:
(7*1)+(6*5)+(5*1)+(4*2)+(3*0)+(2*4)+(1*7)=65
65 % 10 = 5
So 15120-47-5 is a valid CAS Registry Number.

Structural elucidation of an oxidation product of sedimentary porphyrins by one-pot synthesis of 3-methylphthalimide

Nomoto,Kozono,Mita,Shimoyama

, p. 1975 - 1976 (2001)

One-pot synthesis of 3-methylphthalimide was achieved from 1,2,3-trimethylbenzene. The starting compound was oxidized in two steps to produce methylphthalic acids. The o-isomer was converted into its anhydride, which was subjected to thermal reaction with urea to form 3-methylphthalimide. The product was identical with the reported oxidation product of sedimentary porphyrins.

Inclusion complex containing epoxy resin composition for semiconductor encapsulation

-

, (2014/03/21)

The invention is an epoxy resin composition for sealing a semiconductor, including (A) an epoxy resin and (B) a clathrate complex. The clathrate complex is one of (b1) an aromatic carboxylic acid compound, and (b2) at least one imidazole compound represented by formula (II): wherein R2 represents a hydrogen atom, C1-C10 alkyl group, phenyl group, benzyl group or cyanoethyl group, and R3 to R5 represent a hydrogen atom, nitro group, halogen atom, C1-C20 alkyl group, phenyl group, benzyl group, hydroxymethyl group or C1-C20 acyl group. The composition has improved storage stability, retains flowability when sealing, and achieves an effective curing rate applicable for sealing delicate semiconductors.

Synthesis of 9-Methoxymethyl-18-methyl-2,11-dithiametacyclophane: a Dithiametacyclophane with a Protected Internal Benzylic Functional Group

Lai, Yee-Hing,Tan, Quee-May

, p. 1783 - 1788 (2007/10/02)

A synthetic route to a dithiametacyclophane with a benzylic functional (methoxymethyl) group at C9 is described.The benzylic function however had to be introduced at a later stage in the synthetic scheme to optimize the overall yield.Only the anti isomer of the desired dithiacyclophane (7) was isolated.The entire methoxymethyl group lies within the shielding zone of the opposite benzene ring as indicated in the 1H n.m.r. spectrum.Attempts to convert anti-(7) into the novel aromatic system (5b) by a rearrangement-elimination sequence however failed.
