Check Digit Verification of cas no

The CAS Registry Mumber 1335029-82-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,0,2 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1335029-82:
(9*1)+(8*3)+(7*3)+(6*5)+(5*0)+(4*2)+(3*9)+(2*8)+(1*2)=137
137 % 10 = 7
So 1335029-82-7 is a valid CAS Registry Number.

Refinement of arylthiosemicarbazone pharmacophore in inhibition of mushroom tyrosinase

Melanin play a major role in human skin protection and their biosynthesis is vital. Due to their color, they contribute to the skin pigmentation. Tyrosinase is a key enzyme involved in the first stage of melanin biosynthesis, it catalyzes the transformation of tyrosine into l-dopaquinone. The aim of the present study was to study molecules able to inhibit tyrosinase to be used in treating depigmentation-related disorders. In this study, we targeted arylthiosemicarbazone analogs with the aim to contribute to the identification of the optimal aryl ring to be linked to the thiosemicarbazone moiety. The biological activity was evaluated on commercial mushroom tyrosinase which was purified prior use. The results demonstrated that several of our compounds (1a-h, 1j, 1r and 5) had more potent inhibitory activities than kojic acid which was used as the reference inhibitor.
