Check Digit Verification of cas no

The CAS Registry Mumber 6318-34-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,1 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6318-34:
(6*6)+(5*3)+(4*1)+(3*8)+(2*3)+(1*4)=89
89 % 10 = 9
So 6318-34-9 is a valid CAS Registry Number.

Smiles-type free radical rearrangement of aromatic sulfonates and sulfonamides: Syntheses of arylethanols and arylethylamines

Tada, Masaru,Shijima, Hiroyasu,Nakamura, Masaharu

, p. 2499 - 2505 (2007/10/03)

Smiles-type free radical rearrangements of arenesulfonates and arenesulfonamides are exploited for synthetic purposes. 4-Substituted benzenesulfonates cause Smiles-type rearrangement only when substituted by an electron withdrawing group. Therefore, ipso-sttack by an alkyl radical on arenesulfonates takes place in an electrophilic manner. Arenesulfonamides rearrange only when the amide nitrogen is substituted by an alkoxycarbonyl group, due to the electron withdrawing nature of this group. Sulfonates and the N-ethoxycarbonylsulfonamide derivatives of naphthalene, quinoline, and thiophene cause more rearrangement and show synthetic utility. Aromatic amino acid analogues were synthesized by Smiles-type rearrangement with moderate yields. The radical Smiles-type rearrangement of sulfonate and sulfonamide derivatives can be a useful synthetic route when we understand the electronic character of these reactions.

Arenesulfonylheterocycles (I): Synthesis and reactions of 2-benzenesulfonyl-4,5-dichloropyridazin-3-ones with amines

Kweon, Deok-Heon,Kim, Ho-Kyun,Kim, Jeum-Jong,Chung, Hyun A.,Woo, Song Lee,Kim, Sung-Kyu,Yoon, Yong-Jin

, p. 203 - 211 (2007/10/03)

The direct sulfonylation of 4,5-dichloropyridazin-3-ones with some benzenesulfonyl chlorides in the presence of base in tetrahydrofuran gave only the corresponding N-sulfonylated product. The reaction of 2-benzenesulfonyl-4,5-dichloropyridazin-3-ones with some aliphatic amines under neutral conditions afforded 5-alkylamino-2-benzenesulfonyl-4-chloropyridazin-3-ones and/or the corresponding N-alkyl-benzenesulfonamides.
