Check Digit Verification of cas no

The CAS Registry Mumber 1389252-37-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,9,2,5 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1389252-37:
(9*1)+(8*3)+(7*8)+(6*9)+(5*2)+(4*5)+(3*2)+(2*3)+(1*7)=192
192 % 10 = 2
So 1389252-37-2 is a valid CAS Registry Number.

Synthesis of some novel fused imidazo [2, 1-b] [1, 3] thiazole and imidazo [2, 1-b] thiazolo [5, 4-d] isoxazole derivatives

Jaberi, Hamid Reza,Noorizadeh, Hadi

experimental part, p. 1518 - 1525 (2012/06/01)

In this work we describe the synthesis of some novel fused imidazo [2, 1-b] [1, 3] thiazole derivatives. The reaction of 1, 2-diaminoethane 1 with carbon disulphide in H2O/ETOH as solvent furnishes 4, 5-dihydro-1H-imidazol- 2-thiol 2 under reflux condition. the reaction of 4, 5-dihydro-1H-imidazol-2- thiol on treatment with ethylchloro acetate and aromatic aldehyde in presence of anhydrous sodium acetate and acetic acid as solvent to give (Z)-2- (arylidene)-5, 6-dihydroimidazo [2, 1-b] [1, 3] thiazol-3 (2H)-one 3a-j. Compounds 3a-j was condensed with hydroxylamine to give 3- (aryl)-2, 3, 6, 7-tetrahydroimidazo [2, 1-b] [1, 3] thiazolo [5, 4-d] isoxazole 4a-j. The structures of the new compounds were established by elemental analyses, IR, 1H NMR and 13C NMR data.
