193894-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193894-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,8,9 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 193894-20:
(8*1)+(7*9)+(6*3)+(5*8)+(4*9)+(3*4)+(2*2)+(1*0)=181
181 % 10 = 1
So 193894-20-1 is a valid CAS Registry Number.

Synthesis of sulfamide linked dinucleotide analogues
Micklefield, Jason,Fettes, Kevin J.
, p. 5387 - 5390 (2007/10/03)
Novel sulfamide [-NHSO2NH-] linked dinucleotide analogues d(TnsnT) and d(TnsnA) have been synthesised from 3'- and 5'-amino nucleosides. Treatment of these amino nucleosides with catechol sulfate results in the formation of 2-hydroxyphenyl sulf
