Check Digit Verification of cas no

The CAS Registry Mumber 84993-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,9 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84993-20:
(7*8)+(6*4)+(5*9)+(4*9)+(3*3)+(2*2)+(1*0)=174
174 % 10 = 4
So 84993-20-4 is a valid CAS Registry Number.

Synthesis and applications of a fluorous THP protective group

Wipf, Peter,Reeves, Jonathan T.

, p. 4649 - 4652 (1999)

A recyclable fluorous labeled THP protecting group has been developed that allows for simple purification of small molecules by liquid-liquid extraction with FC-72/MeCN, and of larger or more polar molecules by solid phase extraction with fluorous reverse phase silica gel. In addition, we report a new glycosylation method which uses the Cp2ZrCl2-AgClO4 reagent system to activate an anomeric sulfoxide.
