890532-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 890532-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,5,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 890532-91:
(8*8)+(7*9)+(6*0)+(5*5)+(4*3)+(3*2)+(2*9)+(1*1)=189
189 % 10 = 9
So 890532-91-9 is a valid CAS Registry Number.

Stereoselective synthesis of bis-hydroxy-tetrahydrofurans using cross metathesis
Ramu, Errabelli,Bhaskar,Rao, B. Venkateswara,Ramanjaneyulu
, p. 3401 - 3403 (2006)
A short asymmetric approach for the synthesis of bis-tetrahydrofuran units of various annonaceous acetogenins is described. The key steps of the synthesis are self-cross metathesis and Sharpless asymmetric dihydroxylation.
