Check Digit Verification of cas no

The CAS Registry Mumber 204-97-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 204-97:
(5*2)+(4*0)+(3*4)+(2*9)+(1*7)=47
47 % 10 = 7
So 204-97-7 is a valid CAS Registry Number.

CONDENSATION OF o-PHENYLENEDIAMINE WITH α-DIKETONES. PREPARATION AND PHOSPHORYLATION OF NEW α-DIKETONE MONOANILS

Hafez, Taghrid S.

, p. 341 - 349 (2007/10/02)

Condensation of o-phenylendiamine 5 with N-methylisatine 4b and with benzocoumaranedione 12 under different conditions was studied.Monoanils N-methyl-3-(2-aminophenylimino)-indoline-2-one 6b and benzocoumaran-3-(2-aminophenylimino)-2-one 13 were isolated.Dimethyl phosphite add to anils 6b and/or 13 to give the corresponding quinoxalines 7 and 14 respectively.On the other hand, diethyl phosphite add to carbonyl-oxygen double bond in compounds 6b & 13 to give the respective phosphate adducts 16 & 17a.Structural reasonings are based on chemical and spectroscopic results. Key words: α-Diketones; a-diketone monoanils; schiff base; quinoxaline; dialkyl phosphites; phosphates.
