Check Digit Verification of cas no

The CAS Registry Mumber 39059-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,5 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39059-95:
(7*3)+(6*9)+(5*0)+(4*5)+(3*9)+(2*9)+(1*5)=145
145 % 10 = 5
So 39059-95-5 is a valid CAS Registry Number.

CBr4 as a Halogen Bond Donor Catalyst for the Selective Activation of Benzaldehydes to Synthesize α,β-Unsaturated Ketones

Kazi, Imran,Guha, Somraj,Sekar, Govindasamy

supporting information, p. 1244 - 1247 (2017/03/14)

CBr4 has been employed as a halogen bond donor catalyst for the selective activation of aldehyde, to achieve an efficient solvent- and metal-free CC bond forming reaction in the presence of strong acid sensitive groups such as methoxy, cyanide, ester, and ketal for the synthesis of α,β-unsaturated ketones. This unique capability of CBr4 to act as a halogen bond donor has been explored and established using UV-vis as well as IR spectroscopy. Moreover, this unprecedented methodology enables the synthesis of the pharmaceutically important molecule licochalcone A.
