Check Digit Verification of cas no
The CAS Registry Mumber 161464-55-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,4,6 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 161464-55:
(8*1)+(7*6)+(6*1)+(5*4)+(4*6)+(3*4)+(2*5)+(1*5)=127
127 % 10 = 7
So 161464-55-7 is a valid CAS Registry Number.

Tetrazole compounds. 9. A new approach to tetrazolyl-substituted quinoline derivatives
Fischer
, p. 1529 - 1534 (2007/10/02)
The acid-catalyzed reaction of 1-aryl-5-(2-dimethylaminovinyl)-1H-tetrazoles 2 with arylamines suitably functionalized in the ortho-position resulted in Z-configurated transamination products which were cyclized to novel 3-tetrazolylquinolines by the acti
