673478-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 673478-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,3,4,7 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 673478-97:
(8*6)+(7*7)+(6*3)+(5*4)+(4*7)+(3*8)+(2*9)+(1*7)=212
212 % 10 = 2
So 673478-97-2 is a valid CAS Registry Number.

Synthetic studies towards a novel, chemical stable, abasic site analogue of DNA
Hirtz, Caroline,Leumann, Christian J.
, p. 1203 - 1206 (2007/10/03)
We synthesized the phosphinate 7 via photoaddition of methanol to the α,β unsaturated deoxyribono lactone as the key step, followed by an Arbusov reaction for the introduction of phosphorous. Precursor 7 serves for the synthesis and incorporation into DNA
