182204-97-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 182204-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,2,0 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 182204-97:
(8*1)+(7*8)+(6*2)+(5*2)+(4*0)+(3*4)+(2*9)+(1*7)=123
123 % 10 = 3
So 182204-97-3 is a valid CAS Registry Number.

Selective inversion of the proximal or distal hydroxyl groups in syn,syn-3-[N-(alkoxycarbonyl)ammo] 1,2-diols via cyclic sulfates

Kemp, Scott J.,Bao, Jianming,Pedersen, Steven F.

, p. 7162 - 7167 (2007/10/03)

The formation of cyclic sulfates (4) from syn, syn-3-[N-(benzyloxycarbonyl)amino] 1,2-diols provides a common intermediate to access other diastereomers via two inversion procedures. Thermolysis of the cyclic sulfates in acetonitrile normally leads to inversion of the distal hydroxyl group to form a 1,3-oxazin-2-one (6). Catalytic hydrogenation of the cyclic sulfates under basic conditions (NEt3) results in inversion at the proximal hydroxyl group to form a 1,3-oxazolidin-2-one (5).
