15833-84-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15833-84-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,8,3 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15833-84:
(7*1)+(6*5)+(5*8)+(4*3)+(3*3)+(2*8)+(1*4)=118
118 % 10 = 8
So 15833-84-8 is a valid CAS Registry Number.

Synthesis of 4,4-dialkyltetrahydro-3-furanones
Boeykens,De Kimpe
, p. 1109 - 1112 (1992)
4,4-Dialkyltetrahydro-3-furanones were prepared by ring closure of 3,3-dialkyl-1-bromo-4-chloro-2-butanones under the influence of sodium alkoxides and subsequent aqueous hydrolysis of the resulting 3,3-dialkoxy-4,4-dialkyltetrahydrofurans.
