Check Digit Verification of cas no

The CAS Registry Mumber 409316-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,9,3,1 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 409316-81:
(8*4)+(7*0)+(6*9)+(5*3)+(4*1)+(3*6)+(2*8)+(1*1)=140
140 % 10 = 0
So 409316-81-0 is a valid CAS Registry Number.

Electrochemical chlorination and bromination of electron-deficient C[sbnd]H bonds in quinones, coumarins, quinoxalines and 1,3-diketones

Yu, Dan,Ji, Ruixue,Sun, Zhihui,Li, Wenjie,Liu, Zhong-Quan

supporting information, (2021/11/16)

The electrochemistry-promoted chlorination and bromination of electron-deficient C[sbnd]H bonds was developed, using quinones, coumarins, quinoxalines and 1,3-diketones. This protocol features readily available and safe halogen sources (hydrochloric acid and KBr), high site-selectivity and mild reaction conditions. It could provide an efficient access to a series of chlorinated and brominated quinones, coumarins, quinoxalines and 1,3-diketones.
