1152091-60-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1152091-60-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,0,9 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1152091-60:
(9*1)+(8*1)+(7*5)+(6*2)+(5*0)+(4*9)+(3*1)+(2*6)+(1*0)=115
115 % 10 = 5
So 1152091-60-5 is a valid CAS Registry Number.

Synthesis of fused-ring and attached-ring bis-tetrahydrofurans via Pd-catalyzed carboetherification
Ward, Amanda F.,Wolfe, John P.
, p. 2209 - 2212 (2009)
A five step-synthesis of fused bis-tetrahydrofurans and attached bis-tetrahydrofurans from butadiene diepoxide is described. Two sequential Pd-catalyzed carboetherification reactions between protected 1,2-diols and aryl/alkenyl bromides, each of which for
