142387-30-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142387-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,8 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142387-30:
(8*1)+(7*4)+(6*2)+(5*3)+(4*8)+(3*7)+(2*3)+(1*0)=122
122 % 10 = 2
So 142387-30-2 is a valid CAS Registry Number.

Synthesis of 3'-(5-amino-1,2,3,4-tetrazol-1-yl)-3'-deoxythymidines
Habich
, p. 358 - 360 (2007/10/02)
A one-pot synthesis of the new 3'-(5-amino-1,2,3,4-tetrazol-1-yl)-3,-deoxythymidines from 3,-Azido-3'-deoxythymidine (AZT) is described. The key step is the 1,3-dipolar cycloaddition of hydrazoic acid to intermediate carbodiimides.
