Check Digit Verification of cas no

The CAS Registry Mumber 214038-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,0,3 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 214038-72:
(8*2)+(7*1)+(6*4)+(5*0)+(4*3)+(3*8)+(2*7)+(1*2)=99
99 % 10 = 9
So 214038-72-9 is a valid CAS Registry Number.

2',3'-O-phosphonoalkylidene derivatives of ribonucleosides: Synthesis and reactivity

Endova, Magdalena,Masojidkova, Milena,Budesinsky, Milos,Rosenberg, Ivan

, p. 11151 - 11186 (2007/10/03)

A novel type of nucleotide analogues, the 2',3'-O-(1- diethylphosphono)alkylidene derivatives of ribonucleosides was prepared by redox reaction of diethyl chlorophosphite with various nucleoside orthoesters. Some of these compounds undergo interesting rearrangements when treated with nucleophiles. The configuration of the title compounds was determined by 2D-ROESY experiments. Biological activity of partially protected nucleotide analogues is also discussed.
