Check Digit Verification of cas no

The CAS Registry Mumber 103441-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,4 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103441-24:
(8*1)+(7*0)+(6*3)+(5*4)+(4*4)+(3*1)+(2*2)+(1*4)=73
73 % 10 = 3
So 103441-24-3 is a valid CAS Registry Number.

Transition metal-free protodecarboxylation of electron rich aromatic acids under mild conditions

Fang, Jingxian,Wang, Dangui,Deng, Guo-Jun,Gong, Hang

, p. 4503 - 4506 (2017)

A mild and practical method for the transition metal-free protodecarboxylation of aromatic acids using readily available and safe sodium persulfate as initiator was described. This environment-friendly decarboxylation approach was performed at 60 °C in ethanol and could easily scale up to the gram level with a good yield. In Particular, the tandem reactions of decarboxylation and halogenation were achieved by the addition of the corresponding halogenating reagents to the reaction system.
