4439-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4439-62-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4439-62:
(6*4)+(5*4)+(4*3)+(3*9)+(2*6)+(1*2)=97
97 % 10 = 7
So 4439-62-7 is a valid CAS Registry Number.

STUDIES ON THE CHEMICAL TRANSFORMATIONS OF ROTENOIDS. III. RING CONVERSIONS OF METHYL ROTENONONATE AND β-ROTENONONE

Sakakibara, Jinsaku,Nagai, Shin-ichi,Akiyama, Teppei,Ueda, Taisei,Oda, Noriichi,Kidouchi, Kiyoshi

, p. 423 - 436 (1988)

Ring conversions of methyl rotenononate (2b) and β-rotenonone (3) into rotenonone (1) or 4H-furobenzopyrans (5a-b) were investigated.The Beckmann rearrangement of 2b oxime (6) in PPA provided methyl 3-(benzofuran-5-yl)carbonylamino- (9), 3-(benzofuran-5-yl)aminocarbonyl-2-benzofurancarboxylate (10) and furobenzoxazole (11), whereas 3 oxime (12) gave furo benzoxazole (13) as a single product.Compound 2b underwent ring closure with hydrazines to provide benzofuropyridazin-4(3H)-ones (14a-e).

STUDIES ON THE CHEMICAL TRANSFORMATION OF ROTENOIDS. II. REACTIONS OF ROTENONE AND ROTENONONE WITH PRIMARY AMINES

Sakakibara, Jinsaku,Nagai, Shin-ichi,Akiyama, Teppei,Ueda, Taisei,Oda, Noriichi

, p. 1109 - 1117 (2007/10/02)

The ring transformations of rotenone and rotenonone by primary amines were investigated.The improved synthetic methods for rotenonone were also developed.Rotenone (1) underwent cleavage of C-12a and O-13 linkage to give alkylamines (2a-b), while rotenonone (5) gave 2-alkylcarbamoyl-4-alkylimino-8-methylethenyl-3-(2-hydroxy-4,5-dimethoxy)phenyl-8,9-dihydro-4H-furobenzopyrans (7a-d) as a result of nucleophilic attack on C-12 carbon.Compound 1 was oxidized bynitrosyl chloride or dimethyl sulfoxide in the presence of iodine and sulfuric acid to provide rotenonone (5) in improved yields respectively.
