Check Digit Verification of cas no

The CAS Registry Mumber 2513-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2513-25:
(6*2)+(5*5)+(4*1)+(3*3)+(2*2)+(1*5)=59
59 % 10 = 9
So 2513-25-9 is a valid CAS Registry Number.

Efficient One-Pot Synthesis of 2,2-Dimethyl-2 H -chromenes via Pd(II)-Catalyzed Coupling and SiO 2-Promoted Condensation of o -Halophenols with 2-Methyl-3-buten-2-ol

Tee, Jia Ti,Yaeghoobi, Marzieh,Chee, Chin Fei,Rahman, Noorsaadah Abd.

, p. 1920 - 1927 (2015)

An efficient synthesis of 2,2-dimethyl-2H-chromenes was accomplished by Pd(II)-catalyzed coupling and SiO2-promoted condensation of o-halophenols with 2-methyl-3-buten-2-ol (1,1-dimethylallyl alcohol) in one pot. The method is very general and can be useful for the synthesis of some natural 2,2-dimethyl-2H-chromenes.

2H-chromenes generated by an iron(III) complex-catalyzed allylic cyclization

Calmus,Corbu,Cossy

, p. 1381 - 1386 (2015/05/19)

A straightforward method based on an iron(III) complex-catalyzed cyclization of 2-(1-hydroxyallyl)phenols is reported to access a large variety of 2H-chromenes. This method was applied to the total synthesis of a natural product, tephrowatsin B.

Allenes from 3-Bromo-2H-1-benzopyrans

Gabbutt, Christopher D.,Hepworth, John D.,Heron, B. Mark,Rahman, M.. Moshfiqur

, p. 1733 - 1738 (2007/10/02)

The anionic cleavage of 2H-1-benzopyrans results in the formation of allenes.

The chemistry of Lactarius fuliginosus and Lactarius picinus

De Bernardi,Vidari,Vita Finzi,Fronza

, p. 7331 - 7344 (2007/10/02)

Intact fruit-bodies of the Basidiomycetes Lactarius fuliginosus and L. picinus have been found to contain the stearic acid ester 4b. When the mushrooms are injured 4b is rapidly converted to the acrid free phenol 4a which is then gradually oxidized to a m

NOUVELLES VOIES D'ACCES AUX BENZOPYRANNES-III 2H-BENZO(b)PYRANNES(CHROMENES-3)

Begasse, B.,Corre, M. Le

, p. 3409 - 3412 (2007/10/02)

Alkylation of o-hydroxybenzyl triphenylphosphonium salts with α-halogenated carbonyl compounds, in presence of base, gives chrom-3 enes.
