Check Digit Verification of cas no

The CAS Registry Mumber 82955-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,5 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82955-03:
(7*8)+(6*2)+(5*9)+(4*5)+(3*5)+(2*0)+(1*3)=151
151 % 10 = 1
So 82955-03-1 is a valid CAS Registry Number.

Preparation of Functionalized Diaryl- and Diheteroaryllanthanum Reagents by Fast Halogen–Lanthanum Exchange

Benischke, Andreas D.,Anthore-Dalion, Lucile,Berionni, Guillaume,Knochel, Paul

supporting information, p. 16390 - 16394 (2017/11/28)

Aryl and heteroaryl halides (X=Br, I) undergo a fast and convenient halogen–lanthanum exchange with nBu2LaMe, which leads to functionalized diaryl- and diheteroaryllanthanum derivatives. Subsequent trapping reactions with selected electrophiles, such as ketones, aldehydes, or amides, proceeded smoothly at ?50 °C in THF, affording polyfunctionalized alcohols and carbonyl derivatives. Kinetic competition experiments revealed a similar reactivity trend as for Br/Mg exchange, but 106-times higher rates, making it comparable to Br/Li exchange.
