907217-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 907217-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,7,2,1 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 907217-48:
(8*9)+(7*0)+(6*7)+(5*2)+(4*1)+(3*7)+(2*4)+(1*8)=165
165 % 10 = 5
So 907217-48-5 is a valid CAS Registry Number.

An expeditious enantioselective total synthesis of valilactone
Wu, Yikang,Sun, Ya-Ping
, p. 5748 - 5751 (2007/10/03)
The title compound was synthesized through an expeditious route using Crimmins aldolization to establish the two key stereogenic centers and a hydroxyl group activation (HGA) protocol to construct the anti α,β-disubstituted β-lactone from the corresponding syn aldol.
