Check Digit Verification of cas no

The CAS Registry Mumber 128939-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,3 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128939-50:
(8*1)+(7*2)+(6*8)+(5*9)+(4*3)+(3*9)+(2*5)+(1*0)=164
164 % 10 = 4
So 128939-50-4 is a valid CAS Registry Number.

ACTIVATED NITRILES IN HETEROCYCLIC SYNTHESIS: NOVEL SYNTHESIS OF PYRROLOIMIDAZOLE AND PYRANOIMIDAZOLE DERIVATIVES

Abdelaziz, Mahfouz A.,Moharram, H. H.,Essawy, Samy A.,Mohamed, A. A.

, p. 269 - 273 (2007/10/02)

Several new pyrroloimidazole derivatives (4a,b), (8a,b), (10a,b) and pyranoimidazole derivatives (12a,b), (14a,b) were synthesised via the reaction of each 2-thiohydantoin derivatives (2) and (11) with 3-(2-furanyl) or 3-(2-thienyl)-acryloni
