Check Digit Verification of cas no

The CAS Registry Mumber 1220627-90-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,6,2 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1220627-90:
(9*1)+(8*2)+(7*2)+(6*0)+(5*6)+(4*2)+(3*7)+(2*9)+(1*0)=116
116 % 10 = 6
So 1220627-90-6 is a valid CAS Registry Number.

Regioselective and stereoselective cyclizations of chloropolyols in water: Rapid synthesis of hydroxytetrahydrofurans

Kang, Baldip,Chang, Stanley,Decker, Shannon,Britton, Robert

, p. 1716 - 1719 (2010)

A concise, stereoselective synthesis of functionalized tetrahydrofuranols has been developed that involves heating readily available chloropolyols in water. These reactions are operationally straightforward and chemoselective for the formation of tetrahydrofurans, obviating the need for complicated protecting group strategies. The efficiency of this process is demonstrated in a short asymmetric synthesis of the natural product (+)-goniothalesdiol.
