Check Digit Verification of cas no

The CAS Registry Mumber 873994-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,9,9 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 873994-68:
(8*8)+(7*7)+(6*3)+(5*9)+(4*9)+(3*4)+(2*6)+(1*8)=244
244 % 10 = 4
So 873994-68-4 is a valid CAS Registry Number.

Ammonium iodide-promoted unprecedented arylsulfonylation of quinone with sodium arylsulfinates

Yuan, Jin-Wei,Liu, Shuai-Nan,Qu, Ling-Bo

, p. 6763 - 6772 (2017)

A novel ammonium iodide-promoted arylsulfonylation of quinones with sodium arylsulfinates has been explored. This reaction proceeded smoothly through unique nucleophilic addition reaction and produced the arylsulfonylation products in moderate to good yields. The reactions proceeded efficiently over a broad range of substrates with good regioselectivity and functional group tolerance.
