82203-87-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82203-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,0 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82203-87:
(7*8)+(6*2)+(5*2)+(4*0)+(3*3)+(2*8)+(1*7)=110
110 % 10 = 0
So 82203-87-0 is a valid CAS Registry Number.

Studies on Organic Fluorine Compounds. XLII. Synthesis and Reactions of Phenyltrifluoromethylacetylenes

Kobayashi, Yoshiro,Yamashita, Toshinori,Takahashi, Katsuhiro,Kuroda, Hisashi,Kumadaki, Itsumaro

, p. 4402 - 4409 (2007/10/02)

Phenyltrifluoromethylacetylene (4a) was synthesized by the pyrolysis of triphenylphosphonium α-(trifluoroacetyl)benzylide (3a), which was easily derived from benzyl halide (1a).This method can be used for the synthesis of 4-substituted-phenyltrifluoromethylacetylenes (4).The 1,3-dipolar reaction of 4 with diazomethane and phenyl azide proceeds readily to give trifluoromethylated pyrazoles and triazoles.Keywords - trifluoromethyl; acetylene; 1,3-dipolar reaction; intramolecular Wittig reaction; trifluoroacetylphosphonium ylide; pyrazole; diazomethane; phenyl azide

SYNTHESIS OF ARYLTRIFLUOROMETHYLACETYLENES

Kobayashi, Yoshiro,Yamashita, Toshinori,Takahashi, Katsuhiro,Kuroda, Hisashi,Kumadaki, Itsumaro

, p. 343 - 344 (2007/10/02)

Aryltrifluoromethylacetylenes were synthesized by an intramolecular Wittig reaction of trifluoroacetylarylidenephosphoranes, which were synthesized from arylmethyl halides.
