Check Digit Verification of cas no

The CAS Registry Mumber 805236-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,5,2,3 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 805236-73:
(8*8)+(7*0)+(6*5)+(5*2)+(4*3)+(3*6)+(2*7)+(1*3)=151
151 % 10 = 1
So 805236-73-1 is a valid CAS Registry Number.

Synthesis and reactions of allenic sulfone-modified thymidine: The first allenic sulfone to alkylate deoxyadenosine

Bera, Sanjib,Pathak, Tanmaya

, p. 2147 - 2150 (2007/10/03)

3′-(S)-(allenic sulfonyl)-5?-benzoyl-3?-deoxythymidine has been synthesized from 1-(5-O-trityl-3-O-mesyl-2-deoxy-β-D- threopentofuranosyl) thymine via 3′-(S)-(propargylthio)-5′-trityl- 3′-deoxythymidine in six steps. 3′-(S)-(allenic sulfonyl)-3′- deoxythymidine reacts very efficiently with a wide array of nucleophiles. This is also the first report on the alkylation of adenine moiety by some allenic sulfone modified compounds.
