Check Digit Verification of cas no

The CAS Registry Mumber 91892-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91892-48:
(7*9)+(6*1)+(5*8)+(4*9)+(3*2)+(2*4)+(1*8)=167
167 % 10 = 7
So 91892-48-7 is a valid CAS Registry Number.

Triazines and Related Products. Part 26. Synthesis and Chemistry of Bicyclic Analogues of the Antitumour Drug 2,4,6-Tris(dimethylamino)-1,3,5-triazine (Hexamethylmelamine)

Langdon, Simon P.,Simmonds, Richard J.,Stevens, Malcolm F. G.

, p. 993 - 998 (2007/10/02)

Interaction of 2,4-bis(dimethylamino)-6-hydrazino-1,3,5-triazine (1c) with aryl aldehydes yields a series of aryl hydrazones (4) which cyclise to 3-aryl-5,7-bis(dimethylamino)-1,2,4-triazolotriazines (6) with lead(VI) acetate in dichloromethane.Rearrangement of these bicycles in methanolic sodium hydroxide affords stable isomeric 2-aryl-5,7-bis(dimethylamino)triazolotriazines (7).Selected examples from both series of triazolotriazines were screened against the mouse M5076 reticulum cell sarcoma and P388 leukaemia in vivo but proved to have no antitumour activity.
