Check Digit Verification of cas no

The CAS Registry Mumber 1962-05-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1962-05:
(6*1)+(5*9)+(4*6)+(3*2)+(2*0)+(1*5)=86
86 % 10 = 6
So 1962-05-6 is a valid CAS Registry Number.

New approaches for the synthesis and ctytotoxicity of thiazoles derived from cyclohexanone

Abbas, Nermeen S.,Ahmed, Ebtsam A.

, p. 835 - 843 (2015/02/05)

A new class of substituted thiazole derivatives 6a-c which showed promising anticancer activity was synthesized via the reaction of cyclohexanone with phenylisothiocyanate with a good yield. The latter compounds reacted with benzendiazonium chloride to form corresponding 5-phenylazothiazole derivatives 8a and 8b, respectively. Moreover, the reaction of thiazole derivatives 6a-c with each of elemental sulfur and either of malononitrile or ethyl cyanoacetate gave the thiophene derivatives 10a-e, respectively. Compounds 10a-e were subjected to a series of heterocylclization reactions to give heterocyclic derivatives. Their cytotoxicity against four human tumor cells lines was measured and showed promising anticancer activity.
