189334-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189334-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,3,3 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189334-10:
(8*1)+(7*8)+(6*9)+(5*3)+(4*3)+(3*4)+(2*1)+(1*0)=159
159 % 10 = 9
So 189334-10-9 is a valid CAS Registry Number.

Dispiroketals in synthesis. Part 23. A new route to (+)-D-conduritol B from myo-inositol
Innes, Jean E.,Edwards, Paul J.,Ley, Steven V.
, p. 795 - 796 (2007/10/03)
Using (2S,2′S)-2,2′-diphenyl-6,6′-bi(3,4-dihydro-2H-pyran) to effect a simultaneous protection-resolution of a myo-inositol derivative, a new synthesis of (+)-D-conduritol B has been achieved.
