Check Digit Verification of cas no

The CAS Registry Mumber 138815-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,1 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138815-21:
(8*1)+(7*3)+(6*8)+(5*8)+(4*1)+(3*5)+(2*2)+(1*1)=141
141 % 10 = 1
So 138815-21-1 is a valid CAS Registry Number.

Metal ions do not play a direct role in the formation of carbon-carbon triple bonds during reduction of trihaloalkyls by CrII or V II

Levy, Ophir,Bino, Avi

, p. 15944 - 15947 (2012)

Carbyne radicals: Reactions of trihaloalkyl compounds with Cr2+ or V2+ in aqueous solutions yield alkynes and other products. Stepwise halogen abstractions from the trihaloalkyls form alkyl carbyne triradicals in solution. These radicals undergo coupling reactions, producing triply bonded alkyne molecules (see scheme). This process is not metal-assisted and does not occur in the coordination sphere of the metal ions.
