Check Digit Verification of cas no

The CAS Registry Mumber 2923-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2923-83:
(6*2)+(5*9)+(4*2)+(3*3)+(2*8)+(1*3)=93
93 % 10 = 3
So 2923-83-3 is a valid CAS Registry Number.

Interaction of cycloSal-pronucleotides with cholinesterases from different origins. A structure-activity relationship

Meier, Chris,Ducho, Christian,G?rbig, Ulf,Esnouf, Robert,Balzarini, Jan

, p. 2839 - 2852 (2004)

A large number of cycloSal-nucleotide triesters 1-49 have been studied concerning their ability to inhibit cholinesterases of different origins as well as to inhibit HIV replication in cell culture. It was shown that none of the triesters showed inhibitor

3,5-Di-(tert-Butyl)-6-fluoro-cycloSal-d4TMP - A Pronucleotide with a Considerably Improved Masking Group

Ducho, Christian,Wendicke, Silke,Goerbig, Ulf,Balzarini, Jan,Meier, Chris

, p. 4786 - 4791 (2007/10/03)

A new, considerably improved cycloSal masking group has been developed. This new group combines four desirable properties and has been attached to the anti-HIV drug 2′,3′-dideoxy-2′,3′-didehydrothymidine (d4T, 1) to give 3,5-(di-tert-butyl)-6-fluoro-cycloSal-d4TMP (2i). This phosphate triester has a reasonable chemical half-life, highly selectively released d4TMP, has poor - if any - inhibitory effect on butyrylcholinesterase (BChE), and achieved the TK-bypass.
