Check Digit Verification of cas no

The CAS Registry Mumber 139931-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139931-18:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*1)+(2*1)+(1*8)=153
153 % 10 = 3
So 139931-18-3 is a valid CAS Registry Number.

GERMANIUM-CONTAINING α,β-ACETYLENE ALDIMINES, SYNTHESIS AND REACTION WITH COMPLEX METAL HYDRIDES

Yakovleva, E. V.,Sokolov, V. V.,Stadnichuk, M. D.,Sheshenin, S. A.

, p. 2107 - 2111 (2007/10/02)

A mixture of E- and Z-α,β-acetylene aldimines was obtained by the reaction of 3-triethylgermylpropynal with aliphatic and aromatic amines.Condensation of weakly basic 4-nitro- and 2,6-dichloroanilines only takes place when the reacting substances are heated in the presence of catalytic amounts of p-toluenesulfonic acid.The corresponding secondary germanium-containing amines of the propargylic type are obtained in the reaction of α,β-acetylenic aldimines with complex metal hydrides (lithium aluminohydride and sodium borohydride).Degermylation was not observed in the reaction conditions.
