1049699-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1049699-68-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,6,9 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1049699-68:
(9*1)+(8*0)+(7*4)+(6*9)+(5*6)+(4*9)+(3*9)+(2*6)+(1*8)=204
204 % 10 = 4
So 1049699-68-4 is a valid CAS Registry Number.

A cascade cyclization route to adjacent bistetrahydrofurans from chiral triepoxyfarnesyl bromides
Marshall, James A.,Hann, Ronald K.
, p. 6753 - 6757 (2008/12/22)
(Chemical Equation Presented) A number of isomeric bistetrahydrofuran analogues were prepared from triepoxy farnesyl bromides by a zinc-initiated reduction-elimination and in situ Lewis acid-promoted cascade cyclization.
