609344-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 609344-73-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,9,3,4 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 609344-73:
(8*6)+(7*0)+(6*9)+(5*3)+(4*4)+(3*4)+(2*7)+(1*3)=162
162 % 10 = 2
So 609344-73-2 is a valid CAS Registry Number.

Synthesis of enantiomeric 9-(2′,3′,4′-trihydroxybutyl)adenine derivatives from L-ascorbic and D-isoascorbic acids
Wróblewski, Andrzej E.,Karolczak, Wies?awa
, p. 6075 - 6081 (2007/10/03)
L-Ascorbic and D-isoascorbic acids were employed in syntheses of 9-(2′,3′,4′-trihydroxybutyl)adenines protected at 3′ and 4′ oxygens (all four enantiomers) and at 2′ oxygen (2′S,3′R and 2′S,3′S enantiomers).
