222049-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 222049-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,0,4 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 222049-74:
(8*2)+(7*2)+(6*2)+(5*0)+(4*4)+(3*9)+(2*7)+(1*4)=103
103 % 10 = 3
So 222049-74-3 is a valid CAS Registry Number.

Simple one-pot synthesis of a 2'-tritium labeled C-deoxynucleoside
Lutz, Stefan,Benner, Steven A.
, p. 723 - 726 (2007/10/03)
The deoxygenation and 2'-labeling of a C-ribonucleoside by reductive elimination with tri-n-butyltin hydride[3H] in a one-pot reaction is described. The approach is a safe, simple, efficient, and general method for 2'-labeling of nucleosides.
