Check Digit Verification of cas no
The CAS Registry Mumber 145432-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,4,3 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145432-05:
(8*1)+(7*4)+(6*5)+(5*4)+(4*3)+(3*2)+(2*0)+(1*5)=109
109 % 10 = 9

H-phosphonate DNA synthesis without amino protection
Kung,Jones
, p. 5869 - 5872 (2007/10/02)
DNA synthesis by the H-phosphonate method does not require the use of amino protecting groups. The cytosine amino group, and the guanine O6/N1 positions, do react with the condensing agent to some extent, but these derivatives are cleaved under the standa
