Check Digit Verification of cas no

The CAS Registry Mumber 1338340-31-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,3,4 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1338340-31:
(9*1)+(8*3)+(7*3)+(6*8)+(5*3)+(4*4)+(3*0)+(2*3)+(1*1)=140
140 % 10 = 0
So 1338340-31-0 is a valid CAS Registry Number.

Imidazo[1,2-a]benzimidazole derivatives: XXVIII. Syntheses and heterocyclizations on the basis of 1-allyl-2-aminobenzimidazole

Anisimova,Tolpygin

, p. 1346 - 1353 (2011/12/05)

Addition of hydrogen bromide at the double bond of 1-allyl-2-amino-1H- benzimidazole and 3-alkyl-(benzyl)-1-allyl-2-amino-1H-benzimidazolium halides was studied. The resulting 1-(2-bromopropyl) derivatives were subjected to thermolysis under different conditions, and the structure of dehydrobromination products was determined and proved by independent synthesis via prototropic isomerization of the allyl group by the action of bases.
