Check Digit Verification of cas no

The CAS Registry Mumber 128207-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,0 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128207-16:
(8*1)+(7*2)+(6*8)+(5*2)+(4*0)+(3*7)+(2*1)+(1*6)=109
109 % 10 = 9
So 128207-16-9 is a valid CAS Registry Number.

Chlorination Reaction of Aromatic Compounds and Unsaturated Carbon-Carbon Bonds with Chlorine on Demand

Liu, Feng,Wu, Na,Cheng, Xu

, p. 3015 - 3020 (2021/05/05)

Chlorination with chlorine is straightforward, highly reactive, and versatile, but it has significant limitations. In this Letter, we introduce a protocol that could combine the efficiency of electrochemical transformation and the high reactivity of chlorine. By utilizing Cl3CCN as the chloride source, donating up to all three chloride atom, the reaction could generate and consume the chlorine in situ on demand to achieve the chlorination of aromatic compounds and electrodeficient alkenes.
