Check Digit Verification of cas no

The CAS Registry Mumber 1369928-43-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,9,9,2 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1369928-43:
(9*1)+(8*3)+(7*6)+(6*9)+(5*9)+(4*2)+(3*8)+(2*4)+(1*3)=217
217 % 10 = 7
So 1369928-43-7 is a valid CAS Registry Number.

Remarkable switch in the regiochemistry of the iodination of anilines by N-iodosuccinimide: Synthesis of 1,2-dichloro-3,4-diiodobenzene

Shen, Hao,Vollhardt, K. Peter C.

, p. 208 - 214 (2012)

Direct iodination of anilines by NIS in polar solvents (such as DMSO) affords p-iodinated products with up to >99% regioselectivity. Switching to less polar solvents (such as benzene) in the presence of AcOH inverts this outcome toward dramatically increased or preferential generation of the o-isomers, also with up to >99% regioselectivity. This finding was exploited in the synthesis of 1,2-dichloro-3,4-diiodobenzene. Georg Thieme Verlag Stuttgart - New York.
