Check Digit Verification of cas no

The CAS Registry Mumber 13140-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13140-89:
(7*1)+(6*3)+(5*1)+(4*4)+(3*0)+(2*8)+(1*9)=71
71 % 10 = 1
So 13140-89-1 is a valid CAS Registry Number.

Broad Scope and High-Yield Access to Unsymmetrical Acyclic [11C]Ureas for Biomedical Imaging from [11C]Carbonyl Difluoride

Jakobsson, Jimmy E.,Jana, Susovan,Lu, Shuiyu,Pike, Victor W.,Telu, Sanjay

supporting information, p. 10369 - 10376 (2021/06/07)

Effective methods are needed for labelling acyclic ureas with carbon-11 (t1/2=20.4 min) as potential radiotracers for biomedical imaging with positron emission tomography (PET). Herein, we describe the rapid and high-yield syntheses of unsymmet

A New Convenient Method for the Synthesis of Symmetrical and Unsymmetrical N,N'-Disubstituted Ureas

Izdebski, Jan,Pawlak, Danuta

, p. 423 - 425 (2007/10/02)

A new method is described for the preparation of symmetrically and unsymmetrically disubstituted ureas by aminolysis of bis(4-nitrophenyl) carbonate.The second substitution is slower than the first one, and it is possible to isolate monosubstituted intermediates when equimolar amounts of substrates are used.The reaction of the intermediates with different amines give unsymmetrical derivatives of urea.
