163381-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163381-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,3,8 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 163381-38:
(8*1)+(7*6)+(6*3)+(5*3)+(4*8)+(3*1)+(2*3)+(1*8)=132
132 % 10 = 2
So 163381-38-2 is a valid CAS Registry Number.

Oxidation of Fully Protected Glycals by Hypervalent Iodine Reagents
Kirschning, Andreas
, p. 1228 - 1232 (1995)
A new application of organoiodine(III) is presented.Fully protected glycals are directly converted into 2,3-dihydro-4H-pyran-4-ones by benzene (PhI(OH)OTs, 1).The detailed study reveals that this conversion is independent of the rel
