Check Digit Verification of cas no

The CAS Registry Mumber 440327-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,0,3,2 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 440327-39:
(8*4)+(7*4)+(6*0)+(5*3)+(4*2)+(3*7)+(2*3)+(1*9)=119
119 % 10 = 9
So 440327-39-9 is a valid CAS Registry Number.

Novel enzymatic synthesis of levulinyl protected nucleosides useful for solution phase synthesis of oligonucleotides

Garcia, Javier,Fernandez, Susana,Ferrero, Miguel,Sanghvi, Yogesh S.,Gotor, Vicente

, p. 3533 - 3540 (2007/10/03)

An efficient synthesis of 3′- and 5′-O-levulinyl-2′- deoxy- and 2′-O-alkylribonucleosides has been developed from appropriate nucleosides by enzyme-catalyzed regioselective acylation in organic solvents. Several lipases were screened in combination with a
