10190-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 10190-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,9 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 10190-39:
(7*1)+(6*0)+(5*1)+(4*9)+(3*0)+(2*3)+(1*9)=63
63 % 10 = 3
So 10190-39-3 is a valid CAS Registry Number.

A Convenient Synthesis of 2'-Deoxyuridine
Bhat, K. S.,Rao, A. S.
, p. 678 - 679 (2007/10/02)
Reaction of uridine (2) with 2-acetoxybenzoyl bromide (10) furnishes 3',5'-di-O-acetyl-2'-bromo-2'-deoxyuridine (4).Reaction of 2 with 2-acetoxy-5-nitrobenzoyl chloride (11) furnishes 3',5'-di-O-acetyl-2'-chloro-2'-deoxyuridine (5).The transformation of 4 and 5 to 2'-deoxyuridine (1) is known .
