Check Digit Verification of cas no

The CAS Registry Mumber 669013-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,1 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 669013-15:
(8*6)+(7*6)+(6*9)+(5*0)+(4*1)+(3*3)+(2*1)+(1*5)=164
164 % 10 = 4
So 669013-15-4 is a valid CAS Registry Number.

A novel reagent for the chemical phosphorylation of oligonucleotides

Leuck, Michael,Vagle, Kurt E.,Roach, J. Shawn,Wolter, Andreas

, p. 321 - 324 (2004)

A novel phosphoramidite reagent was developed to convert terminal hydroxyl groups of oligonucleotides into phosphate monoesters. The reagent's appearance as a solid foam is advantageous for its manipulation and handling in solid phase synthesis and improves its thermal stability.
