220753-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220753-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,7,5 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220753-99:
(8*2)+(7*2)+(6*0)+(5*7)+(4*5)+(3*3)+(2*9)+(1*9)=121
121 % 10 = 1
So 220753-99-1 is a valid CAS Registry Number.

From furan to open-chain systems. Synthesis of C1-C9 fragment of tylonolide
Raczko, Jerzy
, p. 10181 - 10186 (2007/10/03)
Stereoselective synthesis of C1-C9 subunit of macrocyclic lactone - tylonolide is presented. Starting from 2-methylfuran and crotyl alcohol, a 2,5-disubstituted furan derivative was synthesized. Its oxidation leads to α,β-unsaturated dicarbonyl intermedia
