21704-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21704-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,0 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21704-31:
(7*2)+(6*1)+(5*7)+(4*0)+(3*4)+(2*3)+(1*1)=74
74 % 10 = 4
So 21704-31-4 is a valid CAS Registry Number.

Synthesis of 3-Alkylcatechols via Intramolecular Cyclization

Miyakoshi, Tetsuo,Togashi, Hiroyasu

, p. 407 - 410 (2007/10/02)

The intramolecular cyclization of 2-alkanoyl-2,5-dimethoxytetrahydrofurans 4 with aqueous acid is described. 3-Alkylcatechols 7 were prepared in generally good yields by boiling the dioxane solution of compounds 4 in the presence of 1 M hydrochloric acid.In addition, 4,5-dioxoalkanals 6 were obtained in good to high yields when the dioxane solution of compounds 4 was treated with 0.1 M hydrochloric acid.
