80680-42-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80680-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80680-42:
(7*8)+(6*0)+(5*6)+(4*8)+(3*0)+(2*4)+(1*2)=128
128 % 10 = 8
So 80680-42-8 is a valid CAS Registry Number.

A SIMPLIFIED STRATEGY FOR THE SYNTHESIS OF DIDEOXYRIBONUCLEOTIDE BLOCKS
Sadana, K. L.,Hruska, F. E.,Loewen, P. C.
, p. 3367 - 3370 (2007/10/02)
The rapid synthesis of dideoxyribonucleotide blocks in 60-85percent isolated yields has been achieved by combining the phosphorylation and condensation steps in a sequential reaction series which also allows the recovery of unreacted nucleotides.
