Check Digit Verification of cas no

The CAS Registry Mumber 669776-71-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,7,7 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 669776-71:
(8*6)+(7*6)+(6*9)+(5*7)+(4*7)+(3*6)+(2*7)+(1*1)=240
240 % 10 = 0
So 669776-71-0 is a valid CAS Registry Number.

2'-deoxycytidines carrying amino and thiol functionality: synthesis and incorporation by Vent (exo-) polymerase.

Roychowdhury, Abhijit,Illangkoon, Heshan,Hendrickson, Cynthia L,Benner, Steven A

, p. 489 - 492 (2007/10/03)

[reaction: see text] The synthesis of 2'-deoxycytidine nucleosides bearing amino and thiol groups appended to the 5-position of the nucleobase via a butynyl linker is described. The corresponding triphosphates were then synthesized from the nucleoside and incorporated into oligonucleotides by Vent (exo(-)) DNA polymerase. The ability of Vent (exo(-)) polymerase to amplify oligonucleotides containing these functionalized cytidine derivatives in a polymerase chain reaction (PCR) was demonstrated for the amino-functionalized derivative.
