Check Digit Verification of cas no
The CAS Registry Mumber 13777-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,7 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13777-22:
(7*1)+(6*3)+(5*7)+(4*7)+(3*7)+(2*2)+(1*2)=115
115 % 10 = 5
So 13777-22-5 is a valid CAS Registry Number.

Herein we report the syntheses and the X-ray structure of [Cs8X27]19- (X = Cl, Br) clusters, the first binary cluster anions isolated in bulk crystal structures. They were obtained by electrostatic capture and face-directed recognition of the prenucleation [CsmCln](n-m)- clusters from water solutions, using [M4(OH)8(OH2)16]8+ (M = ZrIV or HfIV) as the counter cations. These compounds have been thoroughly characterized with a variety of techniques including vibrational spectroscopy and superionic conductivity analysis. This work not only provides structural models for a better understanding of the nucleation of binary materials but also shows that magic number binary clusters adopting a cubic lattice structure do form, in agreement with the time-honored theoretical and spectroscopic predictions.
