138518-17-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138518-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,1 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138518-17:
(8*1)+(7*3)+(6*8)+(5*5)+(4*1)+(3*8)+(2*1)+(1*7)=139
139 % 10 = 9
So 138518-17-9 is a valid CAS Registry Number.

Regiospecific hetero Diels-Alder synthesis of furo[2,3-g] and furo[3,2- g]quinoline-4,9-diones

Cherkaoui, Omar,Nebois, Pascal,Fillion, Houda,Domard, Monique,Fenet, Bernard

, p. 9499 - 9508 (1996)

Diels-Alder reactions of 5- or 6-bromobenzofuran-4,7-diones 7 or 10 towards azadienes 1 afford regiospecifically furo[2,3] or furo[3,2- g]quinoline-4,9-diones 3 or 4. Assignment of the regioisomers, made by 2D NMR 1H-13C HMBC experiments, showed that the regiochemistry of the cycloadditions is under control of the bromine atom position. Calculations by the semiempirical method PM3 of the HOMO and LUMO orbital coefficients of azadienes 1 and quinones 2 indicated that the larger ones are situated at C- 4 for 1 and C 5 for 2.
