Check Digit Verification of cas no

The CAS Registry Mumber 201135-88-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,1,3 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201135-88:
(8*2)+(7*0)+(6*1)+(5*1)+(4*3)+(3*5)+(2*8)+(1*8)=78
78 % 10 = 8
So 201135-88-8 is a valid CAS Registry Number.

Piperidinium diazidotriphenylstannate and quinuclidinium diazidotriphenylstannate

Wharf, Ivor,Wojtowski, Ryszard,Onyszchuk, Mario,Simard, Michel G.

, p. 1791 - 1794 (1997)

Two triphenyltin-azide adducts with cyclic aliphatic amines are shown by X-ray diffraction to be [LH][(C6H5)3Sn(N3)2], where for (I), L = piperidine (C5H11N), and for (II), L = quinuclidine (C7H13N). The anions have quasi-trigonal-bipyramidal symmetry, with the azide groups occupying axial positions. In each case, the azide groups are non-equivalent due to one of them hydrogen bonding with the cation. In (I), the NH2 of the cation hydrogen bonds with azides of adjacent anions forming chains through the lattice. For (II), the asymmetric unit has two cations and anions. One cation singly hydrogen bonds to an azide group of one anion, while the other cation forms a bifurcated hydrogen bond linked to azide groups on the two different anions. The cations have their usual geometries, the piperidinium ion having the expected chair conformation.
