Check Digit Verification of cas no

The CAS Registry Mumber 724733-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,4,7,3 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 724733-04:
(8*7)+(7*2)+(6*4)+(5*7)+(4*3)+(3*3)+(2*0)+(1*4)=154
154 % 10 = 4
So 724733-04-4 is a valid CAS Registry Number.

Fluorous thiols in oligosaccharide synthesis

Jing, Yuqing,Huang, Xuefei

, p. 4615 - 4618 (2007/10/03)

A new, almost odorless fluorous thiol is synthesized, which is utilized to prepare highly fluorinated thioglycosyl donors. These thioglycosides showed excellent reactivities in glycosylation reactions. The fluorous chain, stable under esterification, etherification, deacetylation, and glycosylation conditions, allowed facile purification of the thioglycosides by solid-phase extraction through fluorous silica gel. The fluorous thiol was readily recycled.
