Check Digit Verification of cas no

The CAS Registry Mumber 1228956-29-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,9,5 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228956-29:
(9*1)+(8*2)+(7*2)+(6*8)+(5*9)+(4*5)+(3*6)+(2*2)+(1*9)=183
183 % 10 = 3
So 1228956-29-3 is a valid CAS Registry Number.

The synthesis of highly fluorescent heterocyclic compounds: Pyrido[2',1':2,3]imidazo[4,5-b]quinoline-12-yl cyanides

Rahimizadeh, Mohammad,Pordel, Mehdi,Bakavoli, Mehdi,Eshghi, Hossein

experimental part, p. 266 - 270 (2010/11/05)

The syntheses and fluorescence properties of novel derivatives of pyrido[2',1':2,3]imidazo[4,5-. b]quinoline are described. The key intermediates (4-substituted)(3-hydroxyimino-2,3-dihydroimidazo[1,2-. a]pyridin-2-yliden)methyl cyanides were synthesized by reacting the imidazo[1,2-. a]pyridine with arylacetonitriles via nucleophilic substitution of hydrogen. The compounds were deep violet in colour. Acylation of hydroxyl group led to heterocyclization and gave highly fluorescent pyrido[2',1':2,3]imidazo[4,5-. b]quinoline.
