1258381-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258381-47-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,3,8 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1258381-47:
(9*1)+(8*2)+(7*5)+(6*8)+(5*3)+(4*8)+(3*1)+(2*4)+(1*7)=173
173 % 10 = 3
So 1258381-47-3 is a valid CAS Registry Number.

Approach toward the total synthesis of 5-hydroxyaloin a
Procko, Kristen J.,Li, Hui,Martin, Stephen F.
, p. 5632 - 5635 (2011/03/20)
The synthesis of a thiomethyl analogue of 5-hydroxyaloin A has been achieved using benzyne and naphthyne [4 + 2] cycloadditions with substituted furans. A regiocontrolled cycloaddition was achieved using a silicon tether, and a regioselective ring opening
