19383-02-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19383-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,8 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19383-02:
(7*1)+(6*9)+(5*3)+(4*8)+(3*3)+(2*0)+(1*2)=119
119 % 10 = 9
So 19383-02-9 is a valid CAS Registry Number.

experimental part, p. 283 - 290 (2011/07/09)

Starting from TRIS [2-amino-2-(hydroxymethyl)propane-1,3-diol] via its thia analogue, 2-amino-2- (mercaptomethyl)propane-1,3-diol' double cyclocondensation with formaldehyde, we report a four steps synthesis of the first term in the title series of compounds, bearing the exploitable hydroxymethyl functionality at the C-5 position. Conformational analysis is discussed based on DFT calculations and 1H-DNMR.
