Check Digit Verification of cas no

The CAS Registry Mumber 351341-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,1,3,4 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 351341-22:
(8*3)+(7*5)+(6*1)+(5*3)+(4*4)+(3*1)+(2*2)+(1*2)=105
105 % 10 = 5
So 351341-22-5 is a valid CAS Registry Number.

Nucleoside H-phosphonates. 17. Synthetic and 31P NMR studies on the preparation of dinucleoside H-phosphonothioates

Zain,Stawinski

, p. 6617 - 6622 (1996)

Formation of H-phosphonothioate diesters via condensation of H-phosphonate monoesters with a hydroxylic component in the presence of various coupling agents and possible side reactions that may accompany this process were studied using 31P NMR spectroscopy. Optimal reaction conditions, which eliminate or significantly suppress the side reactions, have been designed and assessed in syntheses of dinucleoside H-phosphonothioate diesters.
