Check Digit Verification of cas no

The CAS Registry Mumber 1402238-83-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,2,3 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1402238-83:
(9*1)+(8*4)+(7*0)+(6*2)+(5*2)+(4*3)+(3*8)+(2*8)+(1*3)=118
118 % 10 = 8
So 1402238-83-8 is a valid CAS Registry Number.

Anti -Selective aminofluorination of alkenes with amidines mediated by hypervalent iodine(III) reagents

Chen, Hui,Kaga, Atsushi,Chiba, Shunsuke

, p. 5481 - 5485 (2016)

anti-Selective aminofluorination of alkenes with amidines was enabled by hypervalent iodine(iii) reagents, affording 4-fluoroalkyl-2-imidazolines. Further reductive ring-opening of the 2-imidazoline moiety could deliver highly functionalized 3-fluoropropane-1,2-diamine derivatives.

Copper-catalyzed aminooxygenation of N-allylamidines with PhI(OAc) 2

Sanjaya, Stephen,Chiba, Shunsuke

supporting information, p. 5342 - 5345 (2013/01/15)

A Cu-catalyzed aminoacetoxylation of N-alkenylamidines has been achieved using PhI(OAc)2 as an oxygen source for synthesis of 4-acetoxymethyl-4,5-dihydroimidazoles, which could be further converted into 2,3-diaminopropanol derivatives using AlH
