Check Digit Verification of cas no

The CAS Registry Mumber 256493-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,4,9 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 256493-89:
(8*2)+(7*5)+(6*6)+(5*4)+(4*9)+(3*3)+(2*8)+(1*9)=177
177 % 10 = 7
So 256493-89-7 is a valid CAS Registry Number.

The synthesis of 5-iodocytidine phosphoramidite for heavy atom derivatization of RNA

Irani, Rostem J.,SantaLucia Jr., John

, p. 8961 - 8964 (2007/10/03)

The synthesis of an RNA phosphoramidite of 5-iodocytidine is reported. This heavy atom cytidine derivative was incorporated into four RNAs. Oligoribonucleotides with 5-iodocytidine will be useful for solving the X-ray crystallographic phase problem and for photochemical cross-linking studies.
