Check Digit Verification of cas no
The CAS Registry Mumber 6990-27-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6990-27:
(6*6)+(5*9)+(4*9)+(3*0)+(2*2)+(1*7)=128
128 % 10 = 8
So 6990-27-8 is a valid CAS Registry Number.

Preparation and proposed structure for bis[bis(dimethylamino)bromoborane]-tris(titanium tetrabromide)
Suliman,Schram
, p. 920 - 922 (1973)
Treatment of [(CH3)2N]2BBr with TiBr4 affords {[(CH3)2N]2BBr}2{TiBr 4}3. The stoichiometry of the latter was established by determination of the reactant ratio and by nucleophilic degradation affording TiBr4·N(CH3)3 and [(CH3)2N]2BBr. A structure is proposed for {[(CH3)2N]2BBr}2{TiBr 4}3 based on infrared assignments and the unusual stoichiometry of this compound.
