Check Digit Verification of cas no

The CAS Registry Mumber 215102-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,1,0 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 215102-91:
(8*2)+(7*1)+(6*5)+(5*1)+(4*0)+(3*2)+(2*9)+(1*1)=83
83 % 10 = 3
So 215102-91-3 is a valid CAS Registry Number.

Four and eight membered metal containing boron-nitrogen-heterocycles. Formation and structures in dependence on the steric requirement of their substituents

Albrecht,Elter,Noltemeyer,Meller

, p. 1514 - 1518 (2008/10/09)

TripB(NRLi)2 (Trip = 2,4,6-triisopropylphenyl, R = Me (IIa), CH2Me (IIb), CHMe2 (IIc), CMe3 (IId) reacts with dibromo(dimethyl)tin to give eight membered (IIIa, IIIb) and four membered metallacycles (IVc and IVd). If tetrahalides (GeCl4, SnCl4) are the reaction partners, the spiro compounds Vc and VId are obtained from IIc and IId resp. The compounds are characterized by their m.s. and n.m.r. (1H, 11B, 13C, 19F, 119Sn) spectra and by elemental analyses. An X-ray structure analysis was performed for IIIa.
