Check Digit Verification of cas no

The CAS Registry Mumber 121195-24-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,9 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121195-24:
(8*1)+(7*2)+(6*1)+(5*1)+(4*9)+(3*5)+(2*2)+(1*4)=92
92 % 10 = 2
So 121195-24-2 is a valid CAS Registry Number.

Synthesis of tetrazole fused azepanes and quantum chemical topology study on the mechanism of the intramolecular cycloaddition reaction

Pino-Gonzalez,Romero-Carrasco,Calvo-Losada,O?a-Bernal,Quirante,Sarabia

, p. 50367 - 50371 (2017/11/10)

The synthesis of novel tetrazolo azepanes from azido nitriles by 1,3 intramolecular dipolar cycloaddition starting from monosaccharide derivatives is described. A quantum chemical topological study on the intramolecular cyclization process has been conducted rendering a pseudo-concerted mechanism. Conformational study was done for the final products which showed a preferential twist boat conformation, theoretically suitable for mannosidase inhibition. However, the tetrazoles showed no significant inhibition of glycosidases.
