Check Digit Verification of cas no

The CAS Registry Mumber 1160168-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,1,6 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1160168-52:
(9*1)+(8*1)+(7*6)+(6*0)+(5*1)+(4*6)+(3*8)+(2*5)+(1*2)=124
124 % 10 = 4
So 1160168-52-4 is a valid CAS Registry Number.

Novel synthesis of pyrano[2,3-d]thiazole, thiazolo[3,2-a]pyridine, and pyrazolo [3′,4′:4,5] thiazolo[3,2-a]pyridine derivatives

El-Hag Ali,Abd El-Rahman,Helal,El-Gaby

experimental part, p. 3023 - 3036 (2009/09/25)

Cyclocondensation of 2-cyanomethyl-4-thiazolidinone (1) with tetracyanoethylene (2) furnished pyrano[2,3-d]thiazole derivative (4). Benzo[e]pyrano[2,3-d]thiazole derivative (6) was obtained by cyclization of compound (1) with salicylaldehyde. In a similar manner, condensation of compound (1) with 2-hydroxy-1-naphthaldehyde in refluxing ethanol yielded naphtho[e]pyrano[2,3-d]thiazole derivative (7). Interaction of compound (9) with benzylidenemalononitriles (10) (1:1 molar ratio) at reflux temperature in ethanol in the presence of piperidine afforded thiazolo[3,2-a]pyridines (12a-c). Treatment of compound (12a) with hydrazines furnished pyrazolo[3′, 4′:4,5] thiazolo[3,2-a]pyridines (14a,b). The reaction of compound (1) with benzyli-denecyanoacetate (16) yielded 5-hydroxythiazolo[3,2-a]pyridine derivative (21). Cyclization of bis(thiazolinone) (23) with benzylidenemalononitriles (10) produced bis(thiazolopyridine) derivatives (25a,b). Copyright Taylor & Francis Group, LLC.
