Check Digit Verification of cas no

The CAS Registry Mumber 785708-07-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,5,7,0 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 785708-07:
(8*7)+(7*8)+(6*5)+(5*7)+(4*0)+(3*8)+(2*0)+(1*7)=208
208 % 10 = 8
So 785708-07-8 is a valid CAS Registry Number.

Combining Eosin y with Selectfluor: A Regioselective Brominating System for Para-Bromination of Aniline Derivatives

Huang, Binbin,Zhao, Yating,Yang, Chao,Gao, Yuan,Xia, Wujiong

, p. 3799 - 3802 (2017/07/26)

A mild, metal-free, and absolutely para-selective bromination of aniline derivatives has been developed in excellent yields, wherein the organic dye Eosin Y is employed as the bromine source in company with Selectfluor. Neither air nor moisture sensitive, this facile reaction proceeds smoothly at room temperature and completes within a short time. Mechanistic studies indicate a radical pathway; therefore, the existence of an in situ generated brominating reagent, "Selectbrom", is postulated, which may reasonably account for the unique regioselectivity for the para-bromination of N-acyl- as well as N-sulfonylanilines.
