55101-24-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55101-24-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,0 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 55101-24:
(7*5)+(6*5)+(5*1)+(4*0)+(3*1)+(2*2)+(1*4)=81
81 % 10 = 1
So 55101-24-1 is a valid CAS Registry Number.

, p. 174 - 175 (2009)
In this paper, we report convenient methods for the synthesis of 4-thiopseudoisocytidine (s4ψiC) and 4-thiopseudouridine (s 4ψ). 1HNMR spectral analysis of these modified nucleosides showed that both s4ψ and ss
