67313-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67313-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,1 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67313-23:
(7*6)+(6*7)+(5*3)+(4*1)+(3*3)+(2*2)+(1*3)=119
119 % 10 = 9
So 67313-23-9 is a valid CAS Registry Number.

A facile and efficient route to 3',5'-diamino-3',5'-dideoxynucleosides
Wentworth P.,Janda
, p. 2097 - 2098 (2007/10/03)
An efficient synthesis of 9-(3',5'-diamino-3'-5'-dideoxy-β-D-ribofuranosyl)adenine is described (40% overall yield); the synthetic route is applicable to all the nucleoside bases and can serve as a general procedure for the synthesis of 3',5'-diaminonucle
